Participants

Reaction Steps

2-n-Butyl-5-chlorobenzofuran (9.5 g., 0.046 mol.) was acylated with 8 g. (0.047 mol.) of anisoyl chloride as described in the procedure of Example 10 to give 2-n-butyl-5-chloro-3-(4'-methoxybenzoyl)benzofuran. Demethylation followed by reaction of the 2-n-butyl-5-chloro-3-(4'-hydroxybenzoyl)benzofuran with epichlorohydrin and subsequent opening of the epoxy compound formed with isopropylamine was carried out as described in the procedures of Examples 9 and 7 to give the title compound.
