Participants

Reaction Steps

A solution of 9-[4-(aminomethyl)phenyl]-8-hydroxythieno[2,3-c]quinolin-4(5H)-one (50 mg, 0.16 mmol) and methanesulfonyl chloride (43 mg, 0.37 mmol) in methylene chloride (5 mL) was stirred at room temperature for 10 min. N,N-diisopropylethylamine (48 mg, 0.37 mmol) was added and the reaction mixture was stirred for 1.5 h, concentrated under reduced pressure and the residue was purified by preparatory HPLC (C18 silica, water/acetonitrile w/0.05% TFA gradient) to afford the desired product (28 mg, 45%) as a white solid: 1H NMR (500 MHz, DMSO-d6) δ 11.77 (s, 1H), 9.22 (s, 1H), 7.70-7.67 (m, 2H), 7.49 (d, J=8.0 Hz, 2H), 7.36 (d, J=8.9 Hz, 1H), 7.23 (d, J=8.0 Hz, 2H), 7.15 (d, J=8.9 Hz, 1H), 5.89 (d, J=5.4 Hz, 1H), 4.29 (d, J=6.4 Hz, 2H), 2.94 (s, 3H); ESI MS m/z 401 [C19H16N2O4S+H]+; HPLC >99% (AUC), tR=12.12 min.
