1-Acetamino

Unless the material is at least partly dried before hydrolysis, the yield of hydrochloride is reduced because of its solubility. If pure 3-broino-4-acetamino-toluene is required, the crude material may be recrystallised from 50 per cent, alcohol with the addition of a little decolourising carbon it separates as colourless needles, m.p. 116-117 (180 g.). [Pg.606]

The mixture obtained is poured into 2 liters of water and the base is precipitated with 30% soda. The precipitated base is extracted with 400 cc of methylene chloride. After evaporation of the solvent, the N-(2-diethylaminoethyl)-2-methoxy-4-acetamino-5-chlorobenzamide formed crystallizes. The melting point is 86°C to 87°C and the yield is 95%. [Pg.1006]

Reaction of estrone 1359 with 1354 and HMDS 2 results in 64% 1360 and 12% 1361 [103]. Reduction of 1360 with Zn/acetic anhydride affords 4-acetaminoes-trone 1362 in 83% yield [103] (Scheme 8.41). [Pg.210]

Bromo-4-aminotoluene hydrochloride. Transfer the partially dried 3-bromo-4-acetamino toluene to a 1-5-litre round-bottomed flask, add 250 ml. of rectified spirit, and reflux on a water bath until the solid dissolves completely. Introduce through the condenser 250 ml. of concentrated hydrochloric acid to the boiling solution and continue the refluxing for a further 3 hours. During this time crystals of 3-bromo-4-aminotoluene hydrochloride separate. Pour the hot mixture into a 1-litre beaker and cool thoroughly. Filter the crystals of the hydrochloride at the pump through a Buchner funnel and wash rapidly with two 50 ml. portions of chilled rectified spirit. The yield of the hydrochloride is 150 g. [Pg.605]
