실험 절차

A mixture of 2-chloro-5-methoxy-1,3-benzothiazole (143 mg), tert-butyl [(1S)-1-methyl-2-(piperidin-4-yloxy)ethyl]carbamate (186 mg), N,N-diisopropylethylamine (93 mg) and DMF (3 mL) was stirred at 150° C. for 1.5 hr under microwave irradiation. Water was added to the reaction mixture, and the obtained mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (194 mg).
