실험 절차

A mixture of dimethyl naphthalene-2,6-dicarboxylate (25.0 g, 102 mmol) and 5% Pd—C (5.0 g) in AcOH (75 mL) was shaken under an atmosphere of hydrogen (ca. 150 p.s.i.) at 80° C. for 6 h. The reaction mixture was cooled, purged with argon, and filtered through a pad of Celite, washing with AcOH. The filtrate was concentrated under reduced pressure to give the title compound. MS: m/z=249 (M+1).
