실험 절차

A mixture of (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-hydroxyethyl)pyridine 1-oxide (206 mg, 0.490 mmol), 1-(4-nitrophenylsulfonyl)-1H-pyrrole-2-carboxylic acid (Int. 5) (160 mg, 0.539 mmol), EDC (282 mg, 1.471 mmol) and DMAP (59.9 mg, 0.490 mmol) in DCM (10 ml) was stirred at RT for 24 hours. The reaction was diluted with DCM and washed with 1N HCl, sat. NaHCO3 (40 ml), and finally with brine. The organic phase was dried over sodium sulfate and the solvent was removed under vacuum; the crude was purified by preparative HPLC-Method 1 to yield (S)-3,5-dichloro-4-(2-(3-(cyclopropylmethoxy)-4-(difluoromethoxy)phenyl)-2-(1-(4-nitrophenylsulfonyl)-1H-pyrrole-2-carbonyloxy)ethyl)pyridine 1-oxide (Int. 6) (95 mg, 0.136 mmol, MS/ESI+698.05 [MH]+, [αD]=−40.97, c=0.6, DCM).
