反応手順

To a solution of methyl-4-(1-hydroxyethyl)benzoate (2.00 g, 11.10 mmol) in a mixture of THF (20 mL) and MeOH (10 mL) was added 1 M KOH (13.32 mL, 13.32 mmol). After stirring at room temperature overnight, the solution was diluted with 2 N HCl and extracted with EtOAc (4×). The combined organic layers were dried (MgSO4) and evaporated to give 4-(1-hydroxyethyl)benzoic acid as a colorless solid. 1H NMR (DMSO-d6, 600 MHz) δ 7.86 (d, J=8.6 Hz, 2H), 7.43 (d, J=8.3 Hz, 2H), 4.75 (q, J=6.5 Hz, 1H), 1.30 (d, J=6.6 Hz, 3H). MS: cal'd 167 (MH+), exp 167 (MH+).
