Procedure

Following General Procedure F, N-[4-(8-methoxy-4-oxo-4,5-dihydrothieno[2,3-c]quinolin-9-yl)phenyl]methanesulfonamide (40 mg, 0.10 mmol) was reacted with tribromoborane (3.0 mL) to afford the desired product (3.8 mg, 10%) as an off-white solid: 1H NMR (500 MHz, CD3OD) δ 7.61 (d, J=5.4 Hz, 1H), 7.44-7.43 (m, 2H), 7.39 (d, J=5.4 Hz, 1H), 7.29-7.27 (m, 2H), 7.16 (d, J=8.4 Hz, 1H), 6.12 (d, J=5.0 Hz, 1H), 3.09 (s, 3); ESI MS m/z 387 [C18H14N2O4S2+H]+; HPLC >99%, tR=9.69 min.
