Reaction Steps

To a solution of 2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido (4,3-b) indole (800 g, 4.0 mmol) in DMF (8 mL), sodium hydride [60% dispersion in oil] (480 mg, 12.0 mmol) was added and the reaction mixture stirred for 5 min. 2,2-Diphenyl oxirane (1.176 g, 6.0 mmol) was added dropwise at RT and reaction mixture was stirred at RT for 16 h. The reaction mixture was poured into ice water and the compound extracted with EtOAc (3×200 mL). The organic layer was washed with water, dried over sodium sulfate and concentrated under vacuum to obtain the crude product. The crude compound was crystallized in ether (50 mL) to obtain 950 mg of white solid product as the free base. 100 mg free base was converted to HCL salt. 1H NMR (DMSO, HCl salt) δ (ppm): 7.50 (d, 2H), 7.30 (m, 3H), 7.20 (m, 5H), 7.10 (s, 1H), 7.05 (d, 1H), 6.70 (d, 1H), 6.08 (bs, 1H), 4.80 (m, 2H), 4.50 (m, 1H), 4.18 (m, 1H), 3.18 (m, 2H), 2.82 (s, 3H), 2.80 (m, 2H), 2.30 (s, 3H).
