To 2 ml of an ethanol solution containing 204.3 mg of 3-ethoxycarbonylmethylimidazo[5,1-b]thiazole, 108.2 mg of hydroxylamine hydrochloride and 210.2 mg of a sodium ethoxide powder were added, and the mixture was then stirred at room temperature for 2 hours. Under ice-cooling, 0.4 ml of 1N hydrochloric acid was added to the reaction solution to neutralize the solution. The solvent was evaporated under reduced pressure, and the resulting residue was purified by Diaion HP-20 Resin to obtain 140 mg of the title compound.
