Procedure
The title compound is prepared according to the method of Example 16 using 2-methyl-5-(2-benzothiazolylmethoxy)-1H-indole-3-acetic acid ethyl ester and 4chlorobenzyl chloride; however, the hydrolysis is carried out in aqueous methanol. Recrystallization from acetonitrile affords white crystals, m.p. 175°-176° C.
