Procedure

The 3-[4-(Benzyloxy)-2-(trifluoromethyl)phenyl]-4-methyl-5-(4-phenylbicyclo[2.2.2]oct-1-yl)-4H-1,2,4-triazole (8-E) (27 mg, 0.05 mmol) was dissolved in ethyl acetate/methanol (1:1, 4 mL) to which 10% palladium-on-carbon (4 mg) was added. The reaction was then placed under hydrogen atmosphere and stirred for 3 h at room temperature and pressure. After appropriate evacuation of the hydrogen atmosphere, the palladium was filtered through a filter aid with methanol (40 mL). The filtrate was collected and the solvent removed in vacuo to afford 4-[4-methyl-5-(4-phenylbicyclo[2.2.2]oct-1-yl)-4H-1,2,4-triazol-3-yl]-3-(trifluoromethyl)phenol (8-F). MS: m/z 428 (M+1); 1H NMR (500 MHz, CDCl3): δ 1.92 (6H, m), 2.11 (6H, m), 3.41 (3H, s), 7.17 (2H, m), 7.24 (1H, m), 7.31 (2H, m), 7.38 (3H, m) ppm.
