Procedure
The 8-[2-(4-isopropyl-1,3-thiazol-2-yl)ethyl]-3-{2-[2-(4-methoxybenzyl)-2H -1,2,3,4-tetrazol-5-yl]acetyl}-2-morpholino-4 H-pyrido[1,2-a]pyrimidin-4-one (8.9 mg, 0.014 mmol) obtained in (D) was dissolved in trifluoroacetic acid (5 ml)and stirred at room temperature for 18 hours. The solvent was evaporated, and the residue was purified by preparative TLC (chloroform:methanol=10:1, v/v) and lyophilized from dioxane to obtain the title compound (4.8 mg, 67.0%) as pale yellow powder.
