実験手順

2.2 g of (Z)-3-(3-methoxy-4-methoxymethoxy-5-propyl-1-naphthyl)-2-methylpropenoic acid was dissolved in 40 ml of acetone, to which 2.5 ml of concentrated hydrochloric acid was added under light-shielding conditions, followed by stirring in a stream of nitrogen at room temperature for 2 hours. The reaction mixture was poured into water, and the resultant crystals were filtered, washed with hexane and dried in vacuo to obtain 1.7 g of the titled compound as yellow crystals.
