Procedure
A mixture of 4-{5-[3-(4-tert-butyl-benzoylamino)-2-methylphenyl]-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino}-benzoic acid ethyl ester (6) (460 mg; 0.86 mmol), 1N NaOH (10 mL), and ethanol (10 mL) was heated at reflux for 1.5 h. The mixture was cooled to room temperature, the resulting slurry was washed with ethyl acetate (2×40 mL), and the ethyl acetate was decanted off. The aqueous slurry was taken to pH 5 with 1N HCl, filtered, washed with water and then diethyl ether to yield 4-{5-[3-(4-tert-butyl-benzoylamino)-2-methyl-phenyl]-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino}-benzoic acid (7) as a light brown solid (248 mg), MS 510.34 (M+H).
