To a solution of tert-butyl 5-(benzylcarbamoyl)-4-methylthiazol-2-yl(methyl)carbamate (0.030 g, 0.083 mmol) in dichloromethane (1 mL) was added trifluoroacetic acid (1 mL) and the resultant mixture was stirred at ambient temperature for 4 h. Toluene (0.5 mL) was added and the reaction mixture was concentrated in vacuo. The residue was triturated with diethyl ether and concentrated in vacuo and dried in vacuum. The crude N-benzyl-4-methyl-2-(methylamino)thiazole-5-carboxamide was obtained and used directly in the next step.
