Reaction Steps
2,3,4,5-tetrahydro-2,8-dimethyl-5-(3-(pyridin-2-yl)prop-2-ynyl)-1H-pyrido[4,3-b]indole (See Example 61A) (20 mg, 0.06 mmol) was hydrogenated in methanol (2 ml) with 10% Pd—C (10 mg) at 1 atm of hydrogen to obtain 5 mg of 2,3,4,5-tetrahydro-2,8-dimethyl-5-(3-(pyridin-2-yl)propyl)-1H-pyrido[4,3-b]indole after purification on neutral alumina chromatography eluting with methanol-dichloromethane gradient. The free base was converted into its diHCl salt by treatment of ethanolic HCl.
