Procedure

To a solution of tert-butyl 4-({[2-(acetylamino)-1,3-thiazol-4-yl]carbonyl}amino)phenylcarbamate (85 mg) in methanol (1 ml) was added 4N hydrogen chloride in ethyl acetate (1 ml), and the mixture was stirred at ambient temperature for 1 hour. The reaction mixture was concentrated in vacuo. The solid residue was collected and washed with ethyl acetate to give 2-(acetylamino)-N-(4-aminophenyl)-1,3-thiazole-4-carboxamide hydrochloride (70 mg).
