Procedure

5.5 g of 1'-hydroxy-8'-methyl-2'-acetonaphthone was dissolved in 50 ml of N,N-dimethylformamide, to which 1.7 g of 60% sodium hydride was added, followed by agitation at 50° C. for 10 minutes. The reaction solution was returned to room temperature, in which 5.5 ml of benzyl chloride was dropped, followed by heating again to 70° C. for reaction for 1 hour. After returning to room temperature, water was added to the solution, which was extracted with ethyl acetate. The resultant organic phase was washed with a saturated saline solution, dried with anhydrous magnesium sulfate and concentrated under reduced pressure. The resultant reside was purified by silica gel column chromatography (15% ethyl acetate/hexane) to obtain 4.8 g of the captioned compound as a brown oily substance.
