Reaction Steps

2-Ethyl-2,3,4,5-tetrahydro-8-methyl-1H-pyrido[4,3-b]indole (214 mg, 1 mmol), 4-methylstyrene oxide (1 mL, 7.5 mmol) and NaH (120 mg, 3 mmol) were heated in DMF (4 mL) at 120° C. for 16 h (overnight) to obtain 50 mg of racemic-2-(2-ethyl-1,2,3,4-tetrahydro-8-methylpyrido[4,3-b]indol-5-yl)-1-p-tolylethanol as a TFA salt after purification by reverse-phase chromatography (C-18, 500 mm×50 mm, Mobile Phase A=0.05% TFA in water, B=0.05% TFA in acetonitrile, Gradient: 10% B to 80% B in 30 min., injection vol. 5 mL). 1H NMR (CDCl3, TFA salt) δ (ppm): 13.20 (bs, 1H), 7.4-7.0 (m, 7H), 5.05-4.97 (m, 1H), 4.70 (t, 1H), 4.25-4.10 (m, 3H), 3.70-3.60 (m, 1H), 3.40-3.10 (m, 5H), 2.5 (s, 3H), 2.38 (s, 3H), 1.41 (t, 3H).
