Reaction Steps

To a solution of 90 mg of 1-(2,2-dimethoxyethyl)-7-(trifluoromethyl)-1,5-naphthyridin-2(1H)-one in 0.72 mL of methyl ethyl ketone, 38 μL of concentrated hydrochloric acid was added, and the mixture was heated under reflux while stirring for 1 hour 30 minutes. The reaction mixture was cooled to room temperature, thereto were added chloroform and a saturated aqueous sodium hydrogen carbonate solution, the organic layer was separated, 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 67 mg of (2-oxo-7-(trifluoromethyl)-1,5-naphthyridin-1(2H)-yl)acetaldehyde as a brown oily substance.
