실험 절차

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, 760 mg of 4-fluoro-N1-(2-methoxyethyl)benzene-1,2-diamine hydrochloride and 330 mg of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride in a mixture of 5 ml of pyridine and 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: 95/05, the residue obtained is purified by preparative HPLC/MS (method 1). After the acetonitrile has been evaporated off, the pH is brought to 8 using sodium bicarbonate (solid), then the aqueous phase is extracted with twice 25 ml of ethyl acetate, and the combined organic phases are dried over anhydrous magnesium sulphate, filtered and concentrated to dryness under reduced pressure. 120 mg of 2-{[5-fluoro-1-(2-methoxyethyl)-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:
