Dissolved 4-[10,11 -dihydro-5-(2-propenyl)-5H-dibenzo[a,d]cyclohepten-5-yl]-1-methyl-1,2,5,6-tetrahydropyridine (0.39 g, 1.2 mmol) in 50 mL of absolute ethanol, and added a teaspoon of Raney nickel paste. Hydrogenated on a Paar shaker at 17 psi of hydrogen pressure for 16 hours. Filtered to remove catalyst, and evaporated filtrate to a solid. Recrystallized crude product from hexane to give 0.20 g (50% yield) of 4-[10,11-dihydro-5-propyl-5H-dibenzo[a,d]cyclohepten-5-yl]-1-methyl-1,2,5,6-tetrahydropyridine as a white solid.
