Reaction Steps

Preparation of the title compound was carried out according to General Method 6. 2-Ethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (See Example 5) (400 mg, 2.0 mmol), 4-methylstyrene oxide (2.01 g, 15 mmol) and NaH (240 mg, 6 mmol) were heated in DMF (6 mL) at 120° C. for 16 h to obtain 120 mg of racemic-2-(2-ethyl-1,2,3,4-tetrahydropyrido[4,3-b]indol-5-yl)-1-p-tolylethanol as a trifluoroacetate 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% 13 to 80% B in 30 min, injection vol. 5 mL).
