Procedure
Add the 5-(2-methyl-benzylidene)-10,11-dihydro-5H-dibenzo [a,d]cycloheptene (0.19 g, 0.64 mmol) to a mixture of 10% Pd/C (0.075 g) suspended in absolute ethanol (4.0 mL) and ethyl acetate (2.0 mL) and hydrogenate under a balloon of hydrogen at room temperature and pressure. Stir for 17 h, remove the catalyst via filtration through a pad of Celite, evaporate the filtrate and pass through a plug of silica gel equilibrated with hexanes. Concentrate the filtrate to give the title product: MS (m/e) 298 (M+). Analysis for C23H22: Calcd: C, 91.99 H, 7.39. Found: C, 91.95 H, 7.39.
