Reaction Steps
A mixture of 0.39 g of 5-(aminomethyl)-2-bromothiazole, 0.30 g of 1,2-dimethyl-3-nitroisothiourea, 0.58 g of cuprous bromide, 0.55 g of anhydrous potassium carbonate and 4 ml of dry acetonitrile was stirred in an oil bath of 60° C. for 45 minutes. The reaction mixture was purified by a column chromatography [developing solvent: dichloromethane-methanol (10:1)] to obtain 1-(2-bromo-5-thiazolylmethyl)-3-methyl-2-nitroguanidine (Compound No. 39), as white solid.
