To a solution of 6-hydroxy-3,4-dihydronaphthalen-1(2H)-one (24.3 g) in acetone (160 mL), benzyl bromide (29.4 mL) and potassium carbonate (31.1 g) were added at room temperature, followed by stirring at 40° C. for 3.5 hours. After filtering off the insoluble matters and concentrating the mixture, the residue was washed with a mixed solvent of tert-butyl methyl ether-hexane (1:4) to thereby give the title compound (34.5 g) having the following physical properties.
