実験手順

To a stirred solution of methyl-3-(1-adamantyl)-4-methoxybenzoate (0.27 g, 0.85 mmol) in THF (30 ml) was added a solution of NaOH (0.04 g) in H2O (1 ml), followed by the addition of EtOH (2 ml). The mixture was refluxed for 4 h, then cooled to room temperature and acidified with 1M HCl solution. The crude product was taken in EtOAc (100 ml) and the organic layer was washed with H2O, and dried over MgSO4 and filtered. The filtrate was evaporated to dryness to give the title product (0.22 g, 85%) as colourless solid. 1H-NMR (CDCl3) 1.77 (s, 6H), 2.03 (s, 3H), 2.09 (s, 6H), 3.89 (s, 3H), 6.88 (d, 1H, J=8.44 Hz), 7.93-7.98 (m, 2H).
