Procedure
3-(2-Chloro-5-thiazolylmethyl)-2-iminothiazolidine (233 mg, 1.0 mmol) and sodium carbonate (120 mg, 1.1 mmol) were dissolved in 10 ml of water, into which, benzoyl chloride (141 mg, 1.0 mmol) dissolved in 5 ml of chloroform was added under cooling with ice, and thereafter stirred at room temperature for 2 hours. The chloroform layer was washed successively with 1% hydrochloric acid and water, dehydrated and dried, chloroform was distilled off, and remaining oil was purified by a silica gel column chromatography to obtain the intended substance. The crude crystal of the intended substance was recrystallized from ethyl acetate. Yield: 101 mg (30%). Melting point: 120° C.
