반응 단계

A mixture of acetamidine hydrochloride (28.8 g., 0.15 mole) and 50% sodium hydroxide (12.0 g., 0.15 mole) in 150 ml. of acetone is stirred for a period of 10 min. to liberate the free base. A solution of styrylsulfonyl chloride (10.1 g., 0.05 mole) in 50 ml. of acetone is added dropwise to the mixture at a temperature of 20°-25° C. with stirring. After further stirring for 10 min., the mixture is concentrated under reduced pressure to remove acetone, the concentrate diluted with 200 ml. of water and acidified with 3N hydrochloric acid to provide a precipitate. The precipitate is collected, dissolved in chloroform and the chloroform extract dried. Evaporation of the chloroform solvent under reduced pressure provides a white solid, m.p. 130°-134° C. which is crystallized from isopropyl acetate affording 8.5 g. (76% yield) of N-(STYRYLSULFONYL)ACETAMIDINE, m.p. 134.5°-137.0° C. (corr.).
