実験手順

A mixture of 3-(4-fluorophenyl)propionic acid (275.1 g, 1.6 mol) and thionyl chloride (300 mL, 4.1 mol) was heated to reflux for 3 h, cooled to room temperature and distilled under aspirator vacuum to give 287.6 g (96%) of 3-(4-fluorophenyl)propionyl chloride as a pale pink oil, b.p., 120°-122° C./15 mm Hg:
