실험 절차

2.81 Grams (21 mmol) of the N-chlorosuccinimide was added little by little to a solution consisting of 3.47 g (20.4 mmol) of a 2-isopropyl-4,5-bis(hydroxymethyl) imidazole and 220 ml of ethanol at a temperature of 40° to 45° C. with stirring over a period of about 25 minutes. The mixture was stirred at the same temperature for two hours to effect the reaction, and then ethanol was distilled off under reduced pressure. The resulting reaction product was washed with water to obtain a pale yellowish powdery crystalline 2-isopropyl-4-chloro-5-(hydroxymethyl) imidazole in an amount of 1.69 g (yield, 47.4%). By using acetonitrile, the recrystallization was effected twice to obtain a colorless crystalline product in pure form. The TLC and spectra of this compound were the same as the properties exhibited by the above-mentioned 2-isopropyl-4-chloro-5-(hydroxymethyl) imidazole.
