الإجراء التجريبي

2,3,4,5-Tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (400 mg, 2.1 mmol), 4-methylstyrene oxide (2.1 g, 15.7 mmol) and NaH (252 mg, 6.3 mmol) were heated in DMF (5 mL) at 120° C. for 16 h to obtain 75 mg of racemic-2-(1,2,3,4-tetrahydro-2-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., inject ion vol. 5 mL). 1H NMR (CDCl3, TFA salt) δ (ppm): 13.45-13.20 (bs, 1H), 7.40-7.05 (m, 8H), 5.0-4.9 (t, 1H), 4.8-4.6 (t, 1H), 4.25-4.05 (m, 3H), 3.70-3.60 (m, 1H), 3.40-3.30 (m, 2H), 3.05 (m, 1H), 3.00-2.91 (m, 3H), 2.3 (s, 3H).
