Procedure

5-Benzyloxy-N-[(4-dimethylaminophenyl)methyl]-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide (0.75 g) was dissolved in methanol (60 mL), and 10% palladium carbon (0.5 g) and ammonium formate (1.5 g) were added. The mixture was stirred at room temperature for one day. The reaction mixture was filtrated, and the filtrate was concentrated. Water was added to the residue, and the precipitated crude crystals were recrystallized from ethyl acetate to give N-[(4-dimethylaminophenyl)methyl]-5-hydroxy-N-(4-isopropylphenyl)-1,2,3,4-tetrahydronaphthalene-1-carboxamide (0.5 g). melting point: 200-202° C.
