Water → Methyl 2,6-dimethylbenzoate

Participants

Reaction Steps

K2CO3 (10.1 mmol, 1.5 equiv.) and dimethyl sulfate (7.4 mmol, 1.1 equiv.) were added at 25° C. to a solution of 2,6-dimethylbenzoic acid (6.7 mmol, 1 equiv.), and the mixture was stirred for 1 h. The solvent was reduced under reduced pressure, the residue was taken up in ethyl acetate (100 ml), and water (20 ml) was added. The phases were separated and the aqueous phase was extracted with ethyl acetate (2×50 ml). The combined organic phases were washed with sat. NaCl solution, dried over Na2SO4 and concentrated under reduced pressure. The crude product was used in the next stage without being purified further. Yield: quantitative
