Procedure

To a suspension of 2-(2-carboxyethyl)-3-oxo-4-[3-[3-(2-methoxyphenyl)ureido]phenyl]-3,4-dihydropyrido[2,3-b]pyrazine (0.15 g) in ethanol (9 ml) was added conc. sulfonic acid (0.9 ml) and the mixture was refluxed for 30 minutes. After cooling, the reaction mixture was neutralized and ethanol was evaporated. Crystalline materials formed were collected, washed with water and dried to give 2-(2-ethoxycarbonylethyl)-3-oxo-4-[3-[3-(2-methoxyphenyl)-ureido]phenyl]-3,4-dihydropyrido[2,3-b]pyrazine (0.12 g).
