Reaction Steps
The product is prepared according to the procedure described in Example 3, using 300 mg of sodium [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate, 248 mg of benzene-1,2-diamine and 330 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 2.5 ml of pyridine and 2.5 ml of dimethylformamide and then in 5 ml of acetic acid. After refluxing for one hour and purification by silica column chromatography, eluent: CH2Cl2/MeOH: gradient from 100/0 to 90/10, 75 mg of 2-(1H-benzimidazol-2-ylmethyl)-6-(morpholin-4-yl)pyrimidin-4(3H)-one are obtained in the form of a beige powder, the characteristics of which are the following:
