A mixture of ethyl 3-(1-naphthyl)propionate (18.01 g) and ethyl formate (8.88 g) was added to a suspension of sodium hydride (57% dispersion in oil, 4.43 g) in 1,2-dimethoxyethane stirred at 5°, and the mixture was stirred at 5° for one hour and allowed to warm to room temperature. Water (300 ml) was added and the mixture was extracted with chloroform and the residual aqueous phase adjusted to pH 4 with hydrochloric acid: the mixture was extracted with ether and the extracts evaporated to give ethyl 2-formyl-3-(1-naphthyl)-propionate (16.05 g) as an oil.
