Procedure

To 0.20 g of 8-(1,3-dioxolan-2-ylmethyl)-2-methoxypyrido(2,3-d)pyrimidin-7(8H)-one, 5 mL of an 80% aqueous trifluoroacetic acid solution was added, and the mixture was stirred at room temperature for 8 hours. To the reaction mixture, a saturated aqueous sodium hydrogen carbonate solution and chloroform were added. The organic layer was separated, and the aqueous layer was extracted with chloroform. The organic layer and the extract were combined, the resultant solution was washed with a saturated aqueous sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure to obtain 0.21 g of (2-methoxy-7-oxopyrido(2,3-d)pyrimidin-8(7H)-yl)acetaldehyde as a yellow oily substance.
