Reaction Steps

{(R)-2-[5-bromo-3-(2,6-difluoro-benzyl)-4-methyl-2,6-dioxo-3,6-dihydro-2H-pyrimidin-1-yl]-1-phenyl-ethyl}-carbamic acid tert-butyl ester (45 mg, 0.082 mmol), 1-benzyl-piperazine (216 mg, 1.23 mmol), and acetonitrile (500 μl) were placed in a microwave vessel and heated at 120° C. for 1 hr by microwave irradiation with stirring. Following concentration, the residue was purified using silica gel chromatography (eluent: hexane/ethyl acetate, 2/1) and dried in a vacuum to afford the 33 mg of the compound as a colorless oil (yield 62%).
