実験手順

To a solution of benzyl 8-(1-(4-cyanobenzyl)piperidin-4-ylcarbamoyl)-3,4-dihydro-1H-pyrido[4,3-b]indole-2(5H)-carboxylate (4a, 50 mg, 91 μmol) in DCM (dichloromethane) (1.0 mL) was added dropwise a solution of HBr/AcOH (48% w/v, 1.0 mL). After the resulting brown reaction mixture was stirred for 30 min, the volatiles were evaporated, MeOH (2 mL) was added and the volatiles evaporated again. The resulting brown residue was dissolved in DMF (1.0 mL) and triethylamine (0.5 mL, 0.36 g, 3.6 mmol) and 4-(trifluoromethyl)benzenesulfonyl chloride (45 mg, 0.2 mmol) were added. The resulting reaction mixture was allowed to stir at room temperature overnight, then poured into saturated sodium bicarbonate solution (20 mL) to give a brown precipitate which was filtered and purified by reverse phase HPLC to provide Compound 24 upon trituration with ethyl ether (18 mg, 31%). 1H NMR (DMSO-d6, 300 MHZ) 11.21 (br s, 1H), 11.18 (br s, 1H), 9.75 (br s, 1H), 8.26 (d, J=7.2 Hz, 1H), 8.07 (d, J=8.3 Hz, 2H), 7.98 (d, J=7.7 Hz, 4H), 7.71 (d, J=8.3 Hz, 2H), 7.57 (d, J=8.5 Hz, 1H), 7.28 (d, J=8.5 Hz, 1H), 4.40 (d, J=8.3 Hz, 4H), 3.55-3.06 (m, 7H), 2.92-2.82 (m, 2H), 2.07 (d, J=10.5 Hz, 2H), 1.78 (q, J=11.3 Hz, 2H) ppm; MS (ES) 622 (M+H).
