5-bromo-1-(2-fluoro-6-trifluoromethyl-benzyl)-6-methyl-1H-pyrimidine-2,4-dione (1.50 g, 3.94 mmol), 1-benzyl-piperazine (5.5 mL, 31.5 mmol), and acetonitrile (1 mL) were placed in a microwave vessel and heated at 120° C. for 1.5 hr by microwave irradiation with stirring. Following concentration, the residue was purified using silica gel chromatography (eluent: hexane/ethyl acetate/dichloromethane, 1/2/1) and dried in a vacuum to afford the 1.48 g of the compound as a white solid (yield 79%). 1H NMR (300 MHz, CDCl3) δ 2.15 (2H, m), 2.31 (3H, s), 2.50 (2H, m), 2.78 (2H, m), 3.52 (3H, s), 3.58 (2H, m), 5.36 (2H, s), 7.19-7.41 (7H, m), 7.53 (1H, d)
