A suspension of 6-methoxy-1-tetralone (99 g) in 48% hydrobromic acid (800 ml) was stirred overnight at 120° C. The reaction mixture was poured into ice water, the resulting solid was sequentially washed with water and hexane-diethyl ether system. To a solution of the resulting 6-hydroxy-3,4-dihydro-2H-naphthalen-1-one (76 g) in N,N-dimethylformamide (400 ml) were sequentially added potassium carbonate (76 g) and benzyl bromide (59 ml), and the solution was stirred for 4 hours at room temperature. The reaction mixture was poured into water, the resulting solid was sequentially washed with water and hexane-diethyl ether system to provide the title compound (110 g).
