5-Hexenoic acid (4.9 g, 42.9 mmol) was refluxed in 80 ml of methanol with catalytic p toluene sulfonic acid monohydrate for 40 hours. The solution was cooled and concentrated then poured into ether/water. The ether layer was dried over sodium sulfate and concentrated to give 4.6 g (35.9 mmol), 84% of the title compound.
