Versuchsvorschrift

A mixture of 6-cyclopropyl-3-(2,4-dimethoxybenzyl)thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (2 g), 4′-(bromomethyl)-3′-fluorobiphenyl-2-carbonitrile (1.8 g), potassium carbonate (1.5 g) and acetonitrile (200 mL) was stirred at 50° C. for 2 hr. Insoluble material was filtered off, and the solvent was evaporated under reduced pressure. The obtained residue was dissolved in trifluoroacetic acid (50 mL), and the mixture was stirred at 50° C. for 2 hr. To the reaction mixture was added toluene (50 mL), and the mixture was concentrated under reduced pressure. To the obtained residue was added ethyl acetate (50 mL), and the mixture was concentrated under reduced pressure. The precipitated solid was collected by filtration to give the title compound as a colorless solid (1.5 g, 64%).
