Participants

Reaction Steps

A suspension prepared by mixing 0.7 g of 3-chloroacetylamino-8-methylcarbostyril, 2.04 g of diethylamine, 1.16 ml of triethylamine in 30 ml of acetonitrile was refluxed by heating for 7.5 hours. The reaction mixture was poured in an ice-water, and the precipitate was collected by filtration, washed with water, and dried. Then the dried precipitate was dissolved in methanol, and converted into hydrochloride by using a concentrated hydrochloric acid-ethanol. Recrystallized from ethanol-water to obtain 0.52 g of 3-(2-diethylaminoacetyl)amino-8-methylcarbostyril hydrochloride. Light yellow powdery substance. Melting point: 250°-252° C. (decomposed).
