Acylation of 5-chloro-2-phenylbenzofuran with anisoyl chloride was accomplished as described in the procedure of Example 10 to give 5-chloro-2-phenyl-3-(4'-methoxybenzoyl)benzofuran which was then demethylated and the product treated with epichlorohydrin as described above. Opening of the epoxide ring with isopropylamine as previously described gave the title compound.
