The treatment of 2,5-dimethyl-4-azaindole with ethyl magnesium bromide, followed by benzyl chloride, gave 3-benzyl-2,5-dimethyl-4-azaindole. Cyanomethylation of 6-unsubstituted, 6-chloro-, and 6-methoxy-4-methyl-7-azaindole with potassium cyanide and formalin in ethanol at 120° gave the corresponding ethyl 3-acetates in 30, 32, and 3 % yields, respectively. No nitrile-containing product was isolated.

Bromo-4-methoxy-A-homo-estra-2,4,5(10)-trien-17-one (44 0. 2g), is dissolved in formic acid, 2 ml of boron trifluoride etherate is added and the mixture is stirred vigorously at 0° for 2 hr. A brown mass ca. 0.12 g) is obtained after evaporation of the solvents at reduced pressure. This material is diluted with water and extracted with chloroform. The chloroform extracts are washed successively with water and saturated salt solution, dried over anhydrous magnesium sulfate and evaporated at reduced pressure to give 95 mg of a product which is purified by filtration through a column of neutral alumina and crystallization of the residue after evaporation of the solvent from ethyl acetate-petroleum ether. The resulting A-homo-estra-l(10),2,4a-triene-4,17-dione (45), mp 143-146°, is identical to the tropone (45) prepared from monoadduct 17-ketone (43a). 

Methoxy-D-Homo-estra-l,3,5(10)-trien-17a-one (96)" (/) Acetic acid (6.4 ml) is added to a stirred solution of estrone methyl ether (93 1.1 g) in ethanol (35 ml) containing potassium cyanide (6 g) at 0°. After being stirred for 1 hr at 0° and 2.5 hr at room temperature, the reactants dissolve and potassium acetate preciptates. Water (65 ml) is added to the reaction mixture and the precipitated solid is collected by filtration. The crude product is dissolved in ethyl acetate and the ethyl acetate solution is washed with water, dried over anhydrous magnesium sulfate and evaporated to dryness under reduced pressure. Recrystallization of a portion of the crude product from cyclohexane-acetone gives 3-methoxy-17a-cyano-estra-l, 3,5(10)-trien-17j5-ol (94a) as needles mp 158.5°.

Benzhydryl 3-carbamoyloxymethyl-7j3-(2-thienylacetamido)-70 -methoxydecephalosporanate (300 mg) in 0.5 ml in anisole and 2.5 ml of trifluoroacetic acid is reacted for 15 minutes at 10°C. The resulting mixture is evaporated at reduced pressure and flushed twice with anisole. The residue is dissolved in methylene chloride and extracted with 5% sodium bicarbonate solution. The aqueous solution is adjusted to pH 1. B with 5% phosphoric acid and extracted with ethyl acetate. The organic solution is dried and evaporated to yield the pure 3-carba-moyloxymethyl-70 -methoxy-7/3-(2-thienylacetamido)decephalosporanic acid, MP 165°C to 167°C. This may then be converted to the sodium salt. 

A mixture of 16.3 g of 4-methyl-6-methoxy-2-pyrimidinyl-hydrazine, 13.7 g of ethyl acetoacetate and 16.3 ml of methanol was refluxed 2 hours on a water bath. After a mixture of 4.7 g of sodium hydroxide, 4.7 ml of water and 27 ml of methanol was added dropwise thereto at about 50°C, the reaction mixture was refluxed for 2 hours more, then methanol was distilled off and the residue was dissolved in 130 ml of water. The solution was adjusted to pH 6 with acetic acid. The precipitate was filtered, washed with water and dried to give 24 g (yield 95.3%) of crystals, MP 97° to 98°C. Recrystallization from ligroin gave 1-(4 -methyl-6 -methoxy-2 -pyrimidinyl)-3-methyl-3-pyrazoline-5-one, MP 102° to 103°C. 

After evaporation of the solvent, a very thick, colorless oil is obtained. This base is dissolved by 200 ml of absolute ethanol and the quantity of HCI to obtain the dihydrochioride is added. It is left for a few hours over ice, dried, washed with approximately 100 ml of anhydrous ether in order to obtain 190 to 195 grams of 1-[2-phenyl-2-methoxy]-ethyl-4-[3-phenyl-3-hydroxy] -propyl-piperazine dihydrochioride after drying at 60°C in vacuo. The yield is 80%. It is recrystallized from absolute ethanol. The product is in the form of white crystalline powder, soluble in water, slightly soluble in alcohol, insoluble in ethyl acetate.
