Procedure
A solution of (R)-9-[4-(1-aminoethyl)phenyl]-8-hydroxythieno[2,3-c]quinolin-4(5H)-one (28 mg, 0.83 mmol) and methanesulfonyl chloride (82 μL, 1.0 mmol) in 1:1 methylene chloride/THF (6 mL) and DMF (1.5 mL) was stirred at room temperature for 10 min followed by the addition of N,N-diisopropylethylamine (170 μL, 1.0 mmol). The reaction mixture was stirred for 1.5 h, concentrated and purified by preparatory HPLC (C18 silica, water/acetonitrile w/0.05% TFA gradient) to afford the desired product (8.9 mg, 2%) as a light brown solid: 1H NMR (500 MHz, CD3OD) δ 7.59-7.55 (m, 2H), 7.53 (d, J=5.5 Hz, 1H), 7.39 (d, J=8.9 Hz, 1H), 7.31-7.30 (m, 2H), 7.16 (d, J=8.9 Hz, 1H), 6.02 (d, J=5.4 Hz, 1H), 4.71 (q, J=4.6 Hz, 1H), 2.82 (s, 3H), 1.62 (d, J=7.0 Hz, 3H); ESI MS m/z 415 [C20H18N2O4S2+H]+; HPLC 96.4% (AUC), tR=10.14 min.
