Procedure

Using General Esterification Method C; 2-methyl-4-bromo-benzoic acid (2.15 g, 10.0 mmols) was refluxed for 3 h with 10 mL COCl2. The resulting solution concentrated under reduced pressure and the crude acyl chloride was combined with benzyl alcohol (1.08 g, 10.0 mmols) and pyridine (1.6 mL, 20.0 mmols) to give the title compound (2.4 g, 80%) after work-up and column chromatography (2-5% EtOAc-hexanes) as a colorless oil.

Workup

concentrationThe resulting solution concentrated under reduced pressure
