To dry dimethylformamide solution (70 ml)of 23.7 g of 2-chloromethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazol (28a)was added 5.30 g of sodium azide, and the mixture was stirred with heating at 80° C. for 16 hours. The reaction mixture was added to ice-water, and extracted with diethyl ether. The organic layer was washed with water and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and 24.2 g of 2-azidomethyl-5-(3,5-dichlorophenylthio)-4-isopropyl-1-methyl-1H-imidazole (29a) was obtained (yield about 100%). mp 84-85° C.
