Procedure

The title compound was prepared according to General Method 2. 2-Ethyl-2,3,4,5-tetrahydro-5-phenethyl-1H-pyrido[4,3-b]indole was prepared from 2-ethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (See Example 5) (100 mg, 0.5 mmol), styrene (1 mL, 8.64 mmol) and NaH (200 mg, 5 mmol) in DMF (4 ml) at 150° C. for 16 h to obtain 15 mg of 2-ethyl-2,3,4,5-tetrahydro-5-phenethyl-1H-pyrido[4,3-b]indole after purification.
