実験手順

A mixture of compound 2,3,4,5-tetrahydro-2,8-dimethyl-1H-pyrido[4,3-b]indole (1.5 g, 7.5 mmol, 1 equiv.) and NaH (252 mg, 10.5 mmol, 1.4 equiv.) in DMF (30 mL) were heated to 120° C. for 1 h. The reaction mixture was cooled to RT and 2-methyl-5-(2-methyloxiran-2-yl)pyridine (2.46 g, 16.5 mmol, 2.2 equiv.) in DMF (17 mL) was added dropwise over 12 min. The temperature was again raised to 120° C. and stirred for 3 h. The reaction mixture was cooled to RT and water (5 mL) was added, diluted with EtOAc (700 mL) and the organic layer was washed with water (3×100 mL) and then with brine, dried over sodium sulfate and concentrated under vacuum. The compound was purified by column chromatography over 230-400 silica gel using a gradient of 10-20% MeOH in EtOAc. Yield: 2.3 g (87%). 1H NMR (DMSO-d6, oxalate salt) δ (ppm): 8.52 (bs, 1H), 7.73-7.71 (d, 1H), 7.31-7.29 (d, 1H), 7.17-7.15 (m, 2H), 6.88-6.86 (d, 1H), 4.34 (bs, 2H), 4.24-4.40 (dd, 2H), 3.47 (bs, 2H), 2.98 (bs, 2H), 2.91 (s, 3H), 2.42 (s, 3H), 2.35 (s, 3H), 1.48 (s, 3H).
