Procedure

The 2-hydroxy-8-[2-(4-isopropyl-1,3-thiazol-2-yl)ethyl]-4 H-pyrido[1,2-a]-pyrimidin-4-one (500 mg) obtained in (A) was dissolved in methylene chloride (20 ml), added with triethylamine (0.26 ml) and p-toluenesulfonyl chloride (360 mg) and stirred for 24 hours under nitrogen atmosphere. The reaction solution was added with morpholine (0.83 ml) and stirred for 12 hours, and the solvent was evaporated. The residue was purified by silica gel column chromatography to obtain the title compound (273 mg).
