실험 절차

To a solution of Et3N (1.4 ml, 10 mmol) and 2-methylthiazol-5-amine hydrochloride (1 g, 6.6 mmol) in DCM (30 mL) was added Ac2O (0.94 mL, 10 mmol). The mixture was stirred at room temperature for 3 h. The reaction solution was concentrated, deposited onto silica gel and loaded onto a silica gel column and eluted with EA to give the title compound (0.8 g, yield: 77%).
