実験手順

8,9-Dichloro-5-(2-hydroxy-2-(pyridin-4-yl)propyl)-2-methyl-2,3,4,4a,5,9b-hexahydro-1H-pyrido[4,3-b]indole (500 mg, 1.2 mmol) was dissolved in thionylchloride (5 mL) and stirred at RT for 5 h. The reaction mixture was concentrated under reduced pressure. The residue was dissolved in N-methyl-2-pyrrolidone (5 mL) and the solution was stirred for 5 min. at RT. Powdered KOH (482 mg, 8.5 mmol) was added and the reaction mixture was heated at 100° C. for 1 h. The progress of reaction was monitored by TLC and NMR. Upon completion, the reaction mixture was cooled at RT, diluted with water and extracted with EtOAc. The organic layer was washed with water, dried over anhydrous sodium sulfate, concentrated under reduced pressure and the residue purified by HPLC. 1H NMR (CD3OD, formate salt) δ (ppm): 8.60 (d, 2H), 7.70 (d, 2H), 7.30 (m, 2H), 7.18 (d, 1H), 4.60 (m, 2H), 3.40 (m, 2H), 3.10 (m, 2H), 2.90 (s, 3H), 2.0 (s, 3H).
