実験手順

To a stirred solution of 7-chloro-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.5 g, 2.265 mmol) in anhydrous DMF was added sodium hydride (271 mg, 3 eq.) portionwise followed by 4-(oxiran-2-yl)pyridine (548 mg, 4.5 mmol) at RT. The reaction mixture was stirred for 12 h. The reaction mixture was quenched with ice water and extracted with EtOAc, the organic layer washed with water, dried on anhydrous sodium sulfate, concentrated under vacuum to obtain crude product that was triturated with diethyl ether to obtain 2-(7-chloro-2-methyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)-1-(pyridin-4-yl)ethanol as solid. 1H NMR (CDCl3, freebase) δ (ppm): 8.53 (d, 2H), 7.2 (m, 3H), 7.14 (d, 1H), 7.05 (d, 1H), 4.82 (t, 1H), 4.03 (d, 2H), 3.4 (q, 2H), 2.85 (m, 1H), 2.76 (m, 1H), 2.64 (m, 2H), 2.37 (s, 3H). Separation by chiral HPLC provided enantiomers 53a and 53b.
