Procedure

To a solution of 3-[4-(3-methoxy-benzyloxy)-2-methyl-6-oxo-6H-pyrimidin-1-yl]-4-methyl-benzoic acid methyl ester from Step A (226 mg, 0.57 mmol) in isopropanol (2 mL) was added N-chlorosuccinimide (84 mg, 0.63 mmol) and 2 drops of dichloroacetic acid. The solution was heated at 60° C. for two hours. The solution was allowed to cool to room temperature and concentrated in vacuo and the residue was partitioned between ethyl acetate and water. The organic layer was washed with water and brine and dried over magnesium sulfate. The slurry was filtered and concentrated to provide the chlorinated product as a light yellow semi-solid (260 mg, quantitative yield). MS (M+H): 429
