실험 절차
1-[2-(3-Methoxy-propyl)-8-methyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl]-2-pyridin-4-yl-propan-2-ol (550 mg, 1.39 mmol) was dissolved in thionyl chloride (5 mL), stirred at RT for 1 h. Progress of the reaction was monitored by TLC/LCMS. After completion of the reaction, excess thionyl chloride was evaporated under vacuum. The solid mass obtained was neutralized with aqueous sodium bicarbonate and the desired compound extracted with EtOAc (100 mL×2). The organic layer was dried over anhydrous sodium sulfate, concentrated under vacuum to obtain crude product, which was purified by silica gel column chromatography (100-200 mesh) using MeOH: DCM (0-10%) as eluent followed by reverse phase HPLC to obtain 35 mg of 2-(3-Methoxy-propyl)-8-methyl-5-(2-pyridin-4-yl-propenyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR (CDCl3, free base) δ (ppm): 8.62 (d, 2H), 7.42 (d, 2H), 7.22 (s, 1H), 7.10 (s, 1H), 7.0 (s, 2H), 3.80 (s, 2H), 3.50 (t, 2H), 3.36 (s, 3H), 2.92 (m, 2H), 2.78 (m, 4H), 2.42 (s, 3H), 2.02 (s, 3H), 1.95 (m, 2H). 1H NMR (CD3OD oxalate salt) δ (ppm): 8.82 (d, 2H), 8.30 (d, 2H), 7.80 (s, 1H), 7.38 (s, 1H), 7.16 (s, 2H), 4.40 (m, 1H), 3.98 (m, 1H), 3.60 (m, 4H), 3.50 (t, 2H), 3.40 (s, 3H), 3.25 (m, 2H), 2.42 (s, 3H), 2.20 (m, 2H), 2.18 (s, 3H).
