Procedure
To a mixture of 6-(3-carbomethoxyphenyl)-5-cyano-3,6-dihydro-4-methyl-2-oxo-1-(2H)-pyrimidinecarboxylic acid, 1-ethyl amide (0.34 g, 1.0 mmol), MeOH (9 mL) and water (3 mL) at 0° C. was added lithium hydroxide (0.84 g, 20.0 mmol). The reaction mixture was stirred for 1 h, acidified to pH 2 with 1 N HCl and extracted with EtOAc. The extract was dried (MgSO4) and concentrated in vacuo to give 6-(3-carboxyphenyl)-5-cyano-3,6-dihydro-4-methyl-2-oxo-1-(2H)-pyrimidinecarboxylic acid, 1-ethyl amide as a colorless solid (0.30 g, 92%): 1H NMR (MeOH-d4, 400 MHz) δ 8.98 (s, 1H), 7.89 (m, 2H), 7.46 (d, 1H, J=7.5 Hz), 7.42 (t, 1H, J=7.5 Hz), 6.12 (s, 1H), 3.16 (m, 2H), 2.06 (s, 3H), 1.03 (t, 3H, J=7.0 Hz).
