Versuchsvorschrift

To a solution of 8-chloro 2-methyl-2,3,4,5-tetrahydro-1H-pyrido (4,3-b) indole (800 g, 3.6 mmol) in 8 mL DMF, was added sodium hydride [60% dispersion in oil] (436 mg, 10.9 mmol) and the reaction mixture was stirred for 5 min. 2,2-Diphenyl oxirane (1.06 g, 5.4 mmol) was added dropwise at RT and reaction mixture stirred at RT for 16 h. The reaction mixture was poured into ice water and the desired 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, which 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 (m, 2H), 7.40 (s, 1H), 7.30 (m, 3H), 7.22 (m, 5H), 7.14 (d, 1H), 6.82 (d, 1H), 6.15 (bs, 1H), 4.82 (d, 2H), 4.55 (m, 1H), 4.38 (m, 1H), 4.20 (m, 1H), 3.56 (m, 1H), 3.20 (m, 2H), 2.86 (s, 3H).
