실험 절차

To a solution of 5-chloro-2-{2-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-2-oxo-ethoxy}-benzenesulfonamide (0.10 g, 0.21 mmol) in dichloromethane (2 mL) was added triethylamine (0.033 mL, 0.23 mmol), 4-dimethylaminopyridine (5 mg, 0.04 mmol) and acetic acid 1-chlorocarbonyl-1-methyl-ethyl ester (0.037 mL, 0.25 mmol). The resulting reaction mixture was stirred at ambient temperature overnight, treated with 0.2 N hydrochloric acid extracted with dichloromethane dried over magnesium sulfate, filtered and concentrated in vacuo to give the crude title compound (0.140 g).
