A mixture of 2,6-diethylbenzyl acetate (2.11 g, 10.2 mmol), MeOH (20 mL), H2O (6 mL), and NaOH (1.99 g, 50 mmol, 5 eq) was stirred at RT overnight. After concentrating, the mixture was extracted with heptane (50 mL). The organic layer was dried (Na2SO4), filtered, and evaporated to give 1.90 g of title product. 1H NMR (300 MHz, CDCl3) δ 1.23 (t, 1H, OH), 1.24 (t, 6H), 1.37 (br s, 1H), 2.79 (q, 4H), 4.75 (d, 2H), 7.09 (d, 2H), 7.21 (dd, 1H). The following compound was prepared by making appropriate substitutions to the above procedure: (2,6-Dimethylphenyl)methanol. 1H NMR (300 MHz, CDCl3) δ 1.25 (t, 1H, OH), 2.41 (s, 6H), 4.72 (d, 2H), 7.0-7.15 (m, 3H).
