実験手順
The process of this example was run as was the process of Example 1, starting with the acid chloride formed from 18.9 g. of 4-(2-piperidinoethoxy)-benzoic acid, hydrochloride, and 20 g. of 6-benzoyloxy-2-(4-benzoyloxyphenyl)-benzo[b]thiophene. The reaction mixture was stirred for 1.5 hours, and was then worked up as described in Example 1 to obtain the desired product as an oil. A small portion of the crude product was crystallized from denatured ethanol to provide an analytical sample, m.p. 230°-233° C., the identity of which was confirmed by nmr analysis.
