An acid chloride was formed from 18.1 g. of 4-(2-pyrrolidinoethoxy)benzoic acid, hydrochloride, as described in Example 1. The acid chloride was used to acylate 20 g. of 6-benzoyloxy-2-(4-benzoyloxyphenyl)benzo[b]thiophene as described above in Example 1, using 53.2 g. of aluminum chloride. A sample of the impure product, a tan foam, was recrystallized from denatured ethanol to obtain an analytical sample, m.p. 218°-222°.
