The excess of N-chlorosuccinimide is destroyed by the addition of about 15 drops of allyl alcohol and 180 ml of water is then added with stirring. This mixture is held at 0°C for about one hour. The precipitated 16/3-methyl-1,4-pregnadiene-9o-chloro-11/3,17o,21-triol-3,20-dione-21-acetate is recovered by filtration. A solution of 250 mg of the chlorohydrin in 5 ml of 0.25N perchloric acid in methanol is stirred for about 18 hours at room temperature to produce 16/3-methyl-9o-chloro-11/3,17o,21-trihydroxy-1,4-pregnadiene-3,20-dione which is recovered by adding water to the reaction mixture and allowing the product to crystallize. Propionic anhydride is then used to convert this material to the dipropionate.

The phenols (no. 30a, 30b, 32) are used as reactants to synthesize several of the company s products, including the benzotriazoles. The 2-chloro-4,6-bls-isopropylam-ino-s-triazine (no. 13) are herbicides the chloro compound is used to control weeds and grass in corn and in milo, and the methoxy compound is used for general plant control. Several esters of 3-(3 ,5 -di-t-butyl-4 -hydroxyphenyl) propionic acid were identified, the most abundant being the octadecyl and methyl esters. 

The sediment concentrations of anthropogenic compounds in the cove were somewhat less variable than upstream this probably reflects the greater bottom uniformity of the cove. Fewer of the plant s compounds were detected in sediment from the channel where the cove leads into the brackish river (Point 18, Figure 1). Found at this location were various phenols (no. 28, 30a, 30b, 31, 33, 38, 39), di-t-butyl-benzoqui-none (no. 57), 3,5-di-t-butyl-4-hydroxy-benzaldehyde (no. 35), three benzotriazoles (no. 6, 10, 12), 4,4 -dichloro-3(trifluoromethyl) carbanilide (no. 77), and 2-chloro-4,6-bis-isopropylamino-s-triazine (no. 14). The only compounds from the plant detected in the sediment sample from the brackish river (Point 19) were the two high molecular weight benzotriazoles (no. 10 and 12) and methyl 3-(3 ,5 -di-t-butyl-4 -hydroxphenyl) propionate (no. 46). 

Dichlorophenoxy)acetic acid, together with the 2-methyl-4-chloro and the 2,4,5-trichloro analogs, 2-(2,4,5-trichlorophenoxy)propionic acid, and many other related compounds, constitute one of the major classes of herbicides, selective primarily to dicotyledonous plants. Monocotyledons,... 

When methanol was added to the ethereal reaction mixtures of benzyli-dene derivatives of 2-aminopyridines 198 (R = H, Me R1 = Ph) and the reaction mixtures were allowed to warm up to ambient temperature and left to stand overnight, 3-chloro-2-phenyl-4//-pyrido[l,2-a]pyrimidin-4-ones 199 (R = H, Me R1 = Ph) and the methyl esters of propionic acids 201 were obtained in 5-10% and 18-32% yields, respectively (84JHC407). 

Reaction of 2-aminopyridines with acrylic acid or methacrylic acid in boiling water for 2-20 hours gave betaine hydrates 262 (R3 = H) in 11-88% yields (Scheme 20) (92KGS80). When 2-aminopyridine reacted with methyl metharylate in acetic acid for 24 hours or 2-aminopyridine and its 5-bromo and 5-chloro derivatives reacted with acrylic acid in boiling toluene for 24 hours or 2-aminopyridine reacted with crotonic acid in boiling toluene for 20 hours, 3-(2-pyridylamino)propionic acid derivatives 263 were the products. When 5-chloro-2-aminopyridine reacted with acrylic...

Omeprazole is obtained [15] by the reaction of acetyl ethyl propionate 1 with ammonia to give ethyl -3-amino-2,3-dimethyl acrylate 2. Compound 2 was converted to to 2,4-dihydroxy-3,5,6-trimethyl pyridine 3 by treatment with methyl diethylmalonate. Treatment of compound 3 with phosphorous oxychloride produced 2,4-dichloro-3,5/6-trimethyl pyridine 4. 4-Chloro-3/5,6-trimethyl pyridine 5 was obtained by treatment of compound 4 with hydrogen. On treatment of compound 5 with hydrogen peroxide and acetic acid, 4-chloro-3,5,6-trimethyl-pyridine-N-oxide 6 was produced. Treatment of compound 6 with acetic anhydride gave 4-chloro-2-hydroxymethyl-3,5-dimethyl pyridine 7 which was converted to 2-hydroxymethyl-3,5-dimethyl-4-methoxypyridine 8 by treatment with sodium methoxide. Compound 8 was treated with thionyl chloride to produce 2-chloromethyl-3,5-dimethyl-4-methoxypyridinc 9. Compound 9 interacts with 5-methoxy-2-mercaptobenzimidazole to give 5-methoxy 2-[((4-methoxy-3,5-dimethyl-2-pyridinyl)methyl)thio]-lH-bcnzimidazole 10 which is oxidized to omeprazole 11.
