A mixture of 2,2-dibutyl-3,4-dihydro-5-methoxy-1(2H)-naphthalenone (2.321 g) and aluminium bromide (7.0 g) in dried benzene (40 ml) was refluxed for 40 minutes and allowed to cool in an ice-water bath. The cooled mixture was poured into a mixture of 1N aqueous hydrochloric acid (150 ml) and diethyl ether (100 ml) with stirring. The organic layer was washed with brine, dried, and concentrated in vacuo to yield 2,2-dibutyl-3,4-dihydro-5-hydroxy-1(2H)-naphthalenone (2.643 g) as a crude syrup.
