Procedure

To a solution of 4-methyl-3-[2-methyl-4-(6-methyl-pyridin-2-ylmethoxy)-6-oxo-6H-pyrimidin-1-yl]-benzoic acid methyl ester from Step A, of Example 13 (100 mg, 0.26 mmol) in isopropanol (1 mL) was added N-chlorosuccinimide (39 mg, 0.29 mmol) and 1 drops of dichloroacetic acid. The solution was heated at 60° C. for two hours. The solution was 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 colorless oil (120 mg, quantitative yield). MS (M+H): 414
