Procedure

To a solution of 3-[5-bromo-4-(2,4-difluoro-benzyloxy)-2-methyl-6-oxo-6H-pyrimidin-1-yl]-4-methyl-benzoic acid from Step C (307 mg, 0.66 mmol) in tetrahydrofuran (2 mL) was added 1,1′-carbonyldiimidazole (162 mg, 1.0 mmol). After stifling at ambient temperature for three hours, N,N-dimethylhydroxylamine HCl (97 mg, 1.0 mmol) and triethylamine (0.18 mL, 1.32 mmol) were added. The solution continued to stir for eighteen hours. The solution was partitioned between ethyl acetate and water. The organic layer was washed with saturated sodium bicarbonate, water, 5% citric acid and brine and dried over magnesium sulfate. The slurry was filtered and concentrated to provide the amide as an oil (86 mg, 26%). MS (M, M+2): 508, 510
