反応手順

To a solution of 5-hexenoic acid (15.2 mL, 0.131 mol) in DCM (375 mL), cooled to 0° C., tert-butanol (176 mL, 1.84 mol) and then 4-dimethylaminopyridine (3.21 g, 26.3 mmol) were added. The mixture was stirred at room temperature for 22 hrs, filtered and concentrated. The residue was redissolved in DCM/n-hexane and concentrated under reduced pressure. The crude oil was purified by flash chromatography (Biotage SP1, EtOAc/n-hexane from 5 to 10%), affording the title product.
