Participants

Reaction Steps

To a solution of 2-allyl-2,3,4,5-tetrahydro-8-methyl-1H-pyrido[4,3-b]indole (1000 mg, 4.42 mmol) in DMF (10 mL) was portionwise added sodium hydride (526 mg, 13.26 mmol). After stirring at RT for 5 min., 4-(oxiran-2-yl)pyridine (669 mg, 5.31 mmol) was added dropwise into the reaction mixture, which was stirred at RT for 16 h. Ice water was added into the reaction mixture and the solid mass obtained was filtered, washed with water (2×10 mL), hexane (2×50 mL) and ether to yield 2-(2-allyl-1,2,3,4-tetrahydro-8-methylpyrido[4,3-b]indol-5-yl)-1-(pyridin-4-yl)ethanol. 1H NMR (CDCl3, freebase) δ (ppm): 8.6 (d, 2H), 7.24 (s, 1H), 7.2 (d, 2H), 7.0 (d, 2H), 5.98 (m, 1H), 5.2 (dd, 2H), 5.0 (m, 1H), 4.1 (m, 2H), 3.6 (dd, 2H), 3.22 (d, 2H), 2.7-2.9 (m, 3H), 2.6 (m, 1H), 2.4 (s, 3H). Separation by chiral HPLC provides enantiomers II-63a-b.
