Reaction Steps

The product is prepared according to the procedure described in Example 3, using 400 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate, 436 mg of 4-chlorobenzene-1,2-diamine and 440 mg N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 3.5 ml of pyridine and 3.5 ml of dimethylformamide and then in 7 ml of acetic acid. After refluxing for thirty minutes and purification by silica column chromatography, eluent: CH2Cl2/MeOH: gradient from 100/0 to 90/10, 260 mg of 2-[(6-chloro-1H-benzimidazol-2-yl)methyl]-6-(morpholin-4-yl)pyrimidin-4(3H)-one are obtained in the form of a white powder, the characteristics of which are the following:
