Procedure

0.4 ml of 2M sodium hydroxide is added to a solution of 310 mg of methyl 2-fluoro-5-({[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetyl}amino)benzoate prepared in Example 57, in 7 ml of methanol. After stirring overnight at ambient temperature, a further 0.4 ml of 2M sodium hydroxide is added and the resulting mixture is brought to reflux for 3 hours. After cooling, the reaction mixture is concentrated under reduced pressure. The evaporation residue is taken up with water. The aqueous phase is extracted with ethyl acetate and then acidified with a 1N aqueous solution of hydrochloric acid (pH=5). The insoluble material is filtered off. The filtrate is concentrated under reduced pressure and then taken up with water and a few drops of a 1N aqueous solution of hydrochloric acid. The precipitate formed is filtered off, rinsed with petroleum ether and concentrated to dryness under reduced pressure. 52 mg of 2-fluoro-5-({[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetyl}amino)benzoic acid are obtained in the form of a pale pink solid, the characteristics of which are the following:
