Reaction Steps

P-Tolylhydrazinehydrochloride (150 mg, 0.94 mmol) and 1,3-dimethyl-3-(2-pyridin-4-yl-allyl)-piperidin-4-one (347 mg, 1.4 mmol) were dissolved in 1,4-dioxane (5 mL). Trifluoroacetic acid (0.3 mL) was added and the reaction mixture was heated to 100° C. for 16 h. The reaction mixture was concentrated under reduced pressure and residue was basified with saturated aqueous sodium bicarbonate. The product was extracted with EtOAc (3×30 mL), organic layer was washed with water (2×20 mL), dried over sodium sulfate and concentrated. The residue was purified by reverse phase chromatography to obtain 15 mg of 2,4,8-trimethyl-4-(2-pyridin-4-yl-allyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole.
