Procedure

To a solution of 2,2-dibutyl-5-(2-cyanobenzyloxy)-1,2,3,4-tetrahydro-1-naphthol (500 mg) in a mixture of ethanol (3.5 ml) and aqueous 6N-sodium hydroxide solution (0.275 ml) was added aqueous 30% hydrogen peroxide (2.62 ml) in one portion at ambient temperature. The mixture was stirred for 5 hours at 50° C. and allowed to stand overnight at ambient temperature. The reaction mixture was diluted with ethyl acetate (40 ml). The separated organic layer was washed with aqueous hydrochloric acid, aqueous sodium bicarbonate solution, and brine, and then dried, and evaporated under reduced pressure. The residue was crystallized from aqueous ethanol to yield 2,2-dibutyl-5-(2-carbamoylbenzyloxy)-1,2,3,4-tetrahydro-1-naphthol (425 mg).
