Procedure

To a suspension of N-[(2-chloro-6-methylphenyl)carbonyl]-4-(1,3-dimethyl-2,4-dioxo-5-pyrimidinyl)-3-methyl-L-phenylalanine methyl ester (0.083 mmol, 40 mg) in ethanol (1 mL) was added aqueous 1.0 N sodium hydroxide (0.2 mL) at room temperature. The mixture was stirred for 2 h at room temperature. Then, the ethanol was removed under reduced pressure and the residue was diluted with water (5 mL). The aqueous solution was washed with diethyl ether (20 mL) to remove any neutral impurities. The aqueous layer was acidified with 1.0 N HCl and the product was extracted into ethyl acetate (2×25 mL). The combined organic extracts were washed with brine solution (50 mL) and were dried over anhydrous magnesium sulfate. Filtration of the drying agent and concentration of the filtrate afforded 34 mg (87% yield) of N-[(2-chloro-6-methylphenyl)carbonyl]-4-(1,3-dimethyl-2,4-dioxo-5-pyrimidinyl)-3-methyl-L-phenylalanine as an amorphous white solid. ES-HRMS m/e calcd for C24H24ClN3O5 (M+Na) 492.1295, found 492.1301.
