Participants

Reaction Steps

To a solution of 8-chloro-2,3-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (500 mg, 2.13 mmol) in 4 mL of DMF was added sodium hydride (256 mg, 6.40 mmol) at 0° C., and stirred for 10 min. 3-(2-methyloxiran-2-yl)pyridine (432 mg, 3.20 mmol) was added and the mixture was stirred at RT for 12 h. The reaction was monitored by TLC and LCMS. The reaction mixture was poured into ice cold water and extracted with EtOAc (2×50 mL). The combined organic layer was washed with water (5×25 mL), dried over anhydrous sodium sulfate, concentrated to obtain the crude product, which was crystallized in n-hexane to obtain 350 mg of 1-(8-chloro-2,3-dimethyl-3,4-dihydro-1H-pyrido[4,3-b]indol-5(2H)-yl)-2-(pyridin-3-yl)propan-2-ol. 1H NMR (CDCl3, freebase) δ (ppm): 8.72 (s, 1H), 8.47 (d, 1H), 7.52 (d, 1H), 7.23 (s, 1H), 6.94 (m, 3H), 4.10 (dd, 2H), 3.65 (m, 1H), 3.40 (m, 1H), 2.86 (m, 2H), 2.38 (s, 3H), 2.36 (m, 1H), 1.62 (s, 3H), 1.07 (d, 3H). Separation by chiral HPLC provided diastereomers II-147a-b.
