Procedure

1-Bromo-2-methyl-2-propene (0.055ml) was added to a stirred suspension of potassium carbonate (0.203 g) and 6-(4-methoxyphenylmethyl)-3-methylthieno[2,3-d]pyrimidine-2,4(1H,3H)-dione (0.15 g) in acetone (5 ml). After 16 h at room temperature, the mixture was diluted with saturated aqueous sodium chloride solution and extracted with ethyl acetate. The organic extracts were dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography over silica, eluting with ethyl acetate:petroleum ether (1:3 then 3:7 then 7:13) to give the title compound (0.11 g).
