実験手順
In 100 ml sulfonylchloride was heated 20.0 g (0.057 mol) of 2-chloro-5-(2-chloro-4-trifluoromethylphenoxy)benzoic acid to reflux for 1 hour, and then thionylchloride was removed by distillation. By vacuum distillation of the residue, 18.2 g (0.049 mol) of 2-chloro-5-(2-chloro-4-trifluoromethylphenoxy)benzoyl chloride was obtained; yield 86.0%, b.p. 142°-155° C./0.35 mmHg, nD25 1.5652.
