Reaction Steps

Preparation of the title compound was carried out according to General Method 5. 2-Ethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (See Example 5) (100 mg, 0.5 mmol), benzyl chloride (158 mg, 1.25 mmol) in diisopropylamine (2 mL) were heated at 80° C. for 12 h to obtain 50 mg of 5-benzyl-2-ethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole as 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% B to 80% B in 30 min, injection vol. 5 mL).
