실험 절차

To a solution of 3-[5-chloro-4-(3-methoxy-benzyloxy)-2-methyl-6-oxo-6H-pyrimidin-1-yl]-4-methyl-benzoic acid methyl ester from Step B (260 mg, 0.6 mmol) in tetrahydrofuran (1 mL) was added 1N sodium hydroxide (1 mL) and the solution was stirred at ambient temperature for three hours. The solution was concentrated in vacuo and the aqueous residue was acidified to pH=2 using 1M HCl. The solution was extracted with ethyl acetate, washed with water and dried over magnesium sulfate. The slurry was filtered and concentrated to a yellow oil (230 mg, 92%). MS (M+H): 415
