实验步骤: To a mixture of 3.75 g. of anilinoacetamide, 2.5 g. of potassium bicarbonate and 40 ml. of ethanol was added dropwise 2.7 g. of cyanogen bromide in 20 ml. of ethanol. This mixture was heated to reflux overnight. On cooling, a light tan precipitate formed in the flask. The precipitate was filtered, washed with ethanol, water, and dried overnight. The yield of product, m.p. 277°-9° C. was 3.3 g. (75%). The mass spectrum of the compound gave a parent ion at m/e 175. An analytical sample was prepared by recrystallization from ethanol-methanol, m.p. 280°-2° C. In this case the ethanol filtrate was basic at the conclusion of the reaction leading to formation of the imidazoline in situ. This product is used in Examples 10 and 11. To a mixture of 3.75 g This mixture was heated to reflux overnight On cooling a light tan precipitate formed in the flask The precipitate was filtered washed with ethanol, water dried overnight The mass spectrum of the compound gave a parent ion at m/e 175
