2,5-Dimethylbenzoic acid → Methyl 2,5-dimethylbenzoate

참여 물질

반응 단계

A colorless, homogeneous solution of 2,5-dimethylbenzoic acid (6.3264 g, 42.1 mmol) and 4 N HCl/1,4-dioxane (11.58 mL, 46.3 mmol) was refluxed under nitrogen. After 2.5 hr, the reaction was cooled to room temperature and concentrated in vacuo. The residue was dissolved in EtOAc (100 mL) and washed with water (40 mL), 1N aq. NaOH (40 mL), water (40 mL) and brine (40 mL), successively. The organic solution was dried over MgSO4 and concentrated in vacuo to give the desired product (5.934 g, 34.7 mmol, 82% yield) as a colorless oil.
