Procedure

A mixture of 5-methoxycarbonyl-3-[2-fluoro-5-(N -methyl-N-phenylcarbamoyl) phenyl]thieno[3,4-d]pyrimidine -2,4(1H,3H)-dione (0.18 g) and lithium hydroxide-monohydrate (0.17 g) in tetrahydrofuran (6 mL)-methanol (3 mL)-water (3 mL) was stirred at room temperature for 2 hours. The reaction mixture was poured into 1 mol/L hydrochloric acid, and the resulting mixture was extracted with ethyl acetate. The extract was washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: methylene chloride/methanol=8/1) to give the title compound (0.12 g).
