Reaction Conditions

Reaction Steps

To anhydrous N,N-dimethylformamide (hereinafter referred to as "DMF") (10.0 g) were added potassium fluoride (0.209 g) and phenacyl bromide (0.647 g), followed by stirring on an oil bath at 25° C. for about 1 minute. 2-Hydroxy-3-hydroxycarbonyl-6-methoxycarbonylnaphthalene (0.80 g) was dissolved in anhydrous DMF (5.20 g) and the resulting solution was added to the reaction solution. After the completion of the reaction, ethyl acetate, diethyl ether and aqueous 5% sodium hydrogencarbonate were added. Then, an insoluble matter was removed by filtration and the residue was partitioned. The organic layer was washed with a saturated sodium chloride aqueous solution and then dried over anhydrous magnesium sulfate. After the desiccant was removed by filtration, the filtrate was concentrated under reduced pressure. The resultant residue was purified by subjecting to silica gel chromatography to obtain 0.57 g of 2-hydroxy-3-phenacyloxycarbonyl-6-methoxycarbonylnaphthalene (DSC analysis value: 177.7° C.).
