Participants

Reaction Steps

A solution of dichloromethane (2 mL), compound 22 (20 mg, 0.075 mmol) and triethylamine (11 μL, 0.079 mmol) was cooled to 0° C. 2-chloro-1-ethane sulfonyl chloride (7 μL, 0.067 mmol) was added and the reaction was allowed to proceed for 1 hour prior to addition of saturated sodium bicarbonate (10 mL) and extraction with dichloromethane (3×10 mL). The combined organic layers were dried with MgSO4, filtered and concentrated in vacuo. The product was purified by preparative RP-HPLC and lyophilized (5.6 mg, 23% yield): 1H NMR (400 MHz, DMSO) δ 10.22 (s, 1H), 8.31 (s, 1H), 7.49 (t, J=7.9, 1H), 7.45 (s, 1H), 7.38 (d, J=7.8, 1H), 7.27 (d, J=7.3, 1H), 6.86 (dd, J=16.4, 10.0, 1H), 6.17 (d, J=16.4, 1H), 6.08 (d, J=9.9, 1H), 5.08 (hept, J=6.7, 1H), 1.50 (d, J=6.7, 6H). 13C NMR (100 MHz, DMSO) δ 155.01, 151.96, 151.19, 144.29, 138.50, 136.32, 133.09, 130.22, 127.79, 123.73, 120.09, 119.20, 96.94, 48.85, 21.73; [M+H]+ calculated for C16H18N6O2S 359.1, found 359.4.
