실험 절차

A mixture of diethyl 1,4-bis[(phenylmethyl)oxy]-2,3-naphthalenedicarboxylate (4.78 g, 9.88 mmol), ethanol (75 ml), and 2N aqueous sodium hydroxide solution (75 ml) was refluxed for 2 hours. The reaction mixture was cooled and evaporated. This was acidified with HCl (2N) and the resulting cream solid was collected by filtration and washed with water. This was dried under vacuum to give the title compound (3.79 g, 8.86 mmol). LC/MS: Rt=3.15, [MH]− 427.
