Participants

Reaction Steps

To a solution of Example 99b (43.2 mg, 0.127 mmol) in dichloromethane (2 mL) was added 2,2,2-trifluoroethanesulfonyl chloride (0.015 mL, 0.140 mmol) and triethylamine (0.053 mL, 0.382 mmol). The mixture was stirred for 18 hours at ambient temperature. The reaction mixture was concentrated and the residue was purified by flash column chromatography (silica gel, 0.5-5% methanol in dichloromethane) to provide the title compound (20.8 mg, 33.7% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 12.00 (s, 1H), 10.16 (s, 1H), 7.25-7.32 (m, 3H), 7.14-7.20 (m, 2H), 6.18-6.24 (m, 1H), 4.36-4.55 (m, 3H), 3.52-3.68 (m, 5H), 3.33-3.45 (m, 2H), 1.79-1.94 (m, 2H), 1.39-1.57 (m, 2H). MS (ESI+) m/z 486.1 (M+H)+.
