실험 절차

A mixture of 4′-{[3-(2,4-dimethoxybenzyl)-2,4-dioxo-6-(2,2,2-trifluoroethyl)-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl]methyl}biphenyl-2-carbonitrile (1.68 g) and trifluoroacetic acid (30 mL) was stirred at 50° C. for 2 hr. To the reaction mixture was added toluene (30 mL), under reduced pressure, and concentrated. The precipitated solid was collected by filtration to give the title compound as a colorless solid (1.8 g, 100%).
