Procedure
A mixture of 4-(adamantan-1-ylmethoxy)-5-chloro-2-fluoro-N—(((S)-3-((4-methoxybenzyl)oxy)pyrrolidin-1-yl)sulfonyl)benzamide (0.17 g, 0.28 mmol) in dichloromethane (18 mL) and water (2 mL) was added 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (0.08 g, 0.36 mmol) at ambient temperature and stirred for 16 h. Water (20 mL) was added and the mixture extracted with ethyl acetate (80 mL×2), the combined organics were washed with brine; dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was filtered through a short silicon gel column, eluted with 5%-60% gradient ethyl acetate in hexanes to give the title compound as colorless solid (0.08 g, 55%): 1H NMR (300 MHz, DMSO-d6) δ 11.73 (s, 1H), 7.70 (d, J=7.5 Hz, 1H), 7.21 (d, J=12.4 Hz, 1H), 5.07 (brs, 1H), 4.32-4.27 (m, 1H), 3.71 (s, 2H), 3.56-3.48 (m, 3H), 3.23-3.19 (m, 1H), 1.99 (s, 3H), 1.93-1.63 (m, 14H); MS (ES+) m/z 487.2, 489.1 (M+1); MS (ES−) m/z 485.3, 487.3 (M−1).
