Participants

Reaction Steps

To a solution of (5-chloro-2-{2-[4-(4-fluoro-benzyl)-(2R,5S)-2,5-dimethyl-piperazin-1-yl]-2-oxo-ethoxy}-phenyl)-methanesulfonamide (0.05 g, 0.10 mmol) in dichloromethane (1 mL) was added acetic acid (0.007 g, 0.12 mmol), (3-(dimethylamino)propyl)ethyl carbodiimide (0.030 g, 0.16 mmol), 4-dimethylaminopyridine (0.019 g, 0.16 mmol) and triethylamine (0.023 g, 0.23 mmol). The reaction was stirred at ambient temperature overnight. The reaction was diluted with dichloromethane, washed with saturated aqueous sodium bicarbonate solution and the aqueous layer back extracted with dichloromethane (3×). The organics were combined, dried over sodium sulfate, filtered and concentrated in vacuo. Chromatography on silica gel gave the title compound (0.039 g, LRMS: 526.20).
