Procedure

The product is prepared according to the procedure described in Stage 3 of Example 1, using 261 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate and 173 mg of 1,2-diamino-4,5-difluorobenzene in place of the 1,2-diamino-4-fluorobenzene. After purification by silica gel column chromatography, elution being carried out with a gradient of pure CH2Cl2 to CH2Cl2/MeOH: 85/15, 150 mg of 2-[(5,6-difluoro-1H-benzimidazol-2-yl)methyl]-6-(morpholin-4-yl)pyrimidin-4(3H)-one are obtained in the form of a light pink solid, the characteristics of which are the following:
