Participants

Reaction Steps

To a mixture of 6-cyclopropyl-3-[2-(4-fluorophenyl)-2-oxoethyl]-1-{[2′-(5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl)biphenyl-4-yl]methyl}thieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (0.1 g), tetrahydrofuran (10 mL) and methanol (10 mL) was added sodium borohydride-(0.038 g), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated, and the residue was extracted with chloroform and saturated aqueous ammonium chloride solution. The chloroform layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The precipitated solid was collected by filtration to give the title compound as colorless crystals (0.074 g, 74%).
