Procedure

120 mg of 2-methoxy-1-(2-methoxyvinyl)naphthalene was dissolved in 4 ml of 2 N hydrochloric acid-tetrahydrofuran (1:1). The obtained mixture was then stirred at 70° C. for 2 hours. The reaction solution was cooled to a room temperature and then diluted with ethyl acetate. The resultant product was washed with water and a saturated sodium chloride aqueous solution. The organic layer was dried over magnesium sulfate and then concentrated under a reduced pressure, so as to obtain 115 mg of (2-methoxynaphthalen-1-yl)acetaldehyde. This compound was used in the following reaction without further purification.
