Procedure
To a solution of 3-(3,4-dihydro-8-methyl-1H-pyrido[4,3-b]indol-2(5H)-yl)propan-1-ol (1000 mg, 4.0983 mmol) in DMF (10 mL) was portionwise added sodium hydride (491.8 mg, 12.25 mmol). After stirring at RT for 5 min, 4-(oxiran-2-yl)pyridine (620 mg, 4.92 mmol) was added dropwise into the reaction mixture, which was stirred at RT overnight. Ice water was added into the reaction mixture and the solid mass filtered, washed with water (2×10 mL) and hexane (2×50 mL). The residue was purified by reverse phase HPLC to yield 3-(3,4-dihydro-5-(2-hydroxy-2-(pyridin-4-yl)ethyl)-8-methyl-1H-pyrido[4,3-b]indol-2(5H)-yl)propan-1-ol. 1H NMR (CD3OD, formate salt) δ (ppm): 8.43 (bs, 2H), 7.39 (d, 2H), 7.23 (s, 1H), 7.2 (d, 1H), 7.0 (d, 1H), 5.07 (t, 1H), 4.48 (bs, 2H), 4.23 (m, 2H), 3.7 (t, 2H), 3.6 (bs, 2H), 3.4 (t, 2H), 3.2 (m, 1H), 2.95-3.03 (m, 1H), 2.4 (s, 3H), 2.03 (bs, 2H). Separation by chiral HPLC provides enantiomers II-75a-b.
