Participants

Reaction Steps

A solution of 9-[4-(1-aminoethyl)phenyl]-8-hydroxythieno[2,3-c]quinolin-4(5H)-one (30 mg, 0.089 mmol) and methanesulfonyl chloride (9.0 μL, 0.11 mmol) in 2:1 methylene chloride/THF (3 mL) was stirred at room temperature for 10 min followed by the addition of N,N-diisopropylethylamine (19 μL, 0.11 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 (7.2 mg, 20%) as an amorphous brown solid: 1H NMR (500 MHz, CD3OD) δ 7.57-7.56 (m, 2H), 7.53 (d, J=5.4 Hz, 1H), 7.39 (d, J=8.9 Hz, 1H), 7.32-7.30 (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 >99%, tR=10.18 min.
