実験手順
Following General Procedure F, tert-butyl 4-(6-chloro-8-methoxy-4-oxo-4,5-dihydrothieno[2,3-c]quinolin-9-yl)phenethylcarbamate (79 mg, 0.25 mmol) was treated with BBr3 (1.0 M in CH2Cl2, 9 mL, 9 mmol) to afford the desired product as a yellow solid (12 mg, 20%). 1H NMR (500 MHz, CD3OD) δ 7.61 (d, J=5.4 Hz, 1H), 7.49 (d, J=8.1 Hz, 2H), 7.31 (d, J=7.0 Hz, 3H), 6.10 (d, J=5.4 Hz, 1H), 3.37-3.27 (m, 2H), 3.12 (t, J=7.6 Hz, 2H); ESI MS m/z 371 [C19H15ClN2O2S+H]+; HPLC 96.9% (AUC), tR=8.83 min.
