実験手順

A mixture of 4-(adamantan-1-ylmethoxy)-2-fluoro-5-vinylbenzoic acid (1.00 g, 3.03 mmol) and 10% palladium on activated carbon (0.10 g) in ethyl acetate (150 mL) was fitted with a hydrogen balloon. The reaction mixture was stirred at ambient temperature for 42 h. The mixture was filtered through a pad of diatomaceous earth, and washed with ethyl acetate (50 mL). The filtrate was concentrated in vacuo, the residue was recrystallized from ethyl acetate and hexanes to afford the title compound as an off-white solid (0.75 g, 74%): 1H NMR (300 MHz, DMSO-d6) δ 12.80 (br s, 1H), 7.63 (d, J=8.6 Hz, 1H), 6.87 (d, J=13.2 Hz, 1H), 3.61 (s, 2H), 5.57 (d, J=7.5 Hz, 2H), 1.99 (s, 3H), 1.75-1.63 (m, 12H), 1.14 (t, J=7.5 Hz, 3H); MS (ES+) m/z 333.2 (M+1).
