Reaction Steps
To a solution of 5-(4-benzyl-piperazin-1-yl)-1-(2-fluoro-6-trifluoromethyl-benzyl)-6-methyl-1H-pyrimidine-2,4-dione (1.48 g, 3.11 mmol) in 10 mL of methanol/dichloromethane (1/1) was added 10% palladium/carbon (280 mg), after which the solution was stirred at room temperature for 5 hrs in a hydrogen atmosphere. Following the removal of palladium/carbon therefrom by filtration through cellite, the solution was concentrated. The residue was purified using amine silica gel chromatography (eluent: dichloromethane/methanol, 30/1→10/1) and dried in a vacuum to afford 934 mg of the compound as a white solid. (yield 79%). 1H NMR (300 MHz, CDCl3) δ 2.32 (3H, s), 2.52 (2H, m), 2.83 (2H, m), 2.96 (2H, m), 3.43 (2H, m), 5.37 (2H, s), 7.22 (1H, d), 7.40 (1H, dd), 7.54 (1H, d)
