Procedure

A solution of 2-[(5-ethoxycarbonylmethoxy-1,2,3,4-tetrahydro-1-naphthyl)methoxycarbonyl]-1,1-diphenylhydrazine (0.17 g) and 1N-aqueous sodium hydroxide (1 ml) in dioxane (1.5 ml) was stirred at room temperature for 30 minutes and partitioned between 5% hydrochloric acid and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and evaporated in vacuo. The residue was washed with isopropanol to afford 2-[(5-carboxymethoxy-1,2,3,4-tetrahydro-1-naphthyl)methoxycarbonyl]-1,1-diphenylhydrazine (0.08 g) as a colorless powder.
