Versuchsvorschrift
(3-Benzyloxy-naphthalen-1-yl)-acetic acid ethyl ester (2.43 g, 7.58 mmol) is dissolved in MeOH (50 ml). Palladium on charcoal (807 mg) is added, and the reaction mixture is stirred at RT under an atmosphere of hydrogen (1 atm) for 14 h. The reaction mixture is filtered. Concentration yields the pure title compound. 1H NMR (DMSO, 400 MHz) δ 1.18 (t, J=7.2 Hz, 3H), 4.05 (s, 2H), 4.10 (q, J=7.2 Hz, 2H), 7.04 (d, J=1.8 Hz, 1H), 7.06 (d, J=1.8, 1H), 7.30 (t, J=7.8, 1H), 7.40 (t, J=7.8, 1H), 7.70 (d, J=7.8, 1H), 7.80 (d, J=7.8 Hz, 1H); ES-MS: 230 [M+H]+.
