Participants

Reaction Steps

To a solution of Example 223C (80.0 mg, 0.189 mmol) in N,N-dimethylformamide (2 mL) was added methanesulfonyl chloride (0.030 mL, 0.379 mmol) and triethylamine (0.158 mL, 1.137 mmol) and the mixture was stirred for 3 hours. The mixture was treated with brine and aqueous sodium bicarbonate and extracted with ethyl acetate (twice). The combined organic layers were dried over magnesium sulfate, filtered, concentrated, and purified on silica gel using an ISCO Companion eluting with heptanes/ethyl acetate (1:9 to 0:10) to give the title compound. 1H NMR (400 MHz, DMSO-d6) δ 1.63-1.74 (m, 1H), 1.91-2.14 (m, 2H), 2.15-2.27 (m, 1H), 2.92-3.00 (m, 4H), 3.74 (s, 3H), 4.32-4.40 (m, 1H), 4.44 (t, J=5.8 Hz, 1H), 6.22 (s, 1H), 6.79 (d, J=6.0 Hz, 1H), 7.03 (d, J=4.9 Hz, 1H), 7.15-7.31 (m, 3H), 8.20 (d, J=4.9 Hz, 1H), 11.73-11.86 (m, 1H). MS (ESI+) m/z 428.1 (M+H)+.
