Procedure

A mixture of 6-ethyl-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 (0.2 g), (aminooxy)acetic acid (0.053 g), NaHCO3 (1.0 g) and ethanol (20 mL) was stirred at 80° C. for 16 hr. To the reaction mixture were added chloroform and water, and the mixture was adjusted to pH 4 with 1N hydrochloric acid. The chloroform layer was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography to give the title compound as a stereoisomer mixture (0.062 g, 27%).
