Reaction Steps

2.36 g of 5-nitro-2-methyl-phenylsulfonyl chloride (0.01 mol) and 1.36 g of imidazole (0.02 mol) were dissolved in 15 ml of pyridine, and the mixture was stirred at 50° C. for 3 hours to react. After the reaction, the reaction mixture was poured into water, and extracted with chloroform. The chloroform layer was washed with water and dehydrated. Evaporation of chloroform gave 1.70 g of 1-(5-nitro-2-methyl-phenylsulfonyl)-imidazole of the m.p. 119°-120° C.
