Reaction Steps

The title compound was prepared according to General Method 2. 2,3,4,5-tetrahydro-2-methyl-5-(4-methylphenethyl)-1H-pyrido[4,3-b]indole was prepared from 2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (See Example 3) (200 mg, 1.07 mmol), 4-methylstyrene (1.41 mL, 10.7 mmol) and NaH (250 mg, 60% dispersion in oil, 6.25 mmol) in DMF (6 ml) at 200° C. for 16 h to obtain 7 mg of 2,3,4,5-tetrahydro-2-methyl-5-(4-methylphenethyl)-1H-pyrido[4,3-b]indole after purification.
