Participants

Reaction Steps

2-n-Butylbezofuran (5.7 g., 0.033 mol.) was acylated with 6.7 g. (0.033 mol.) of 2-chloro-4-methoxybenzoic acid chloride in the presence of 18 g. (0.07 mol.) of stannic chloride as described in the procedure of Example 10 to give 2-n-butyl-3-(2'-chloro-4'-methoxybenzoyl)benzofuran. The subsequent demethylation, epoxy compound formation and ring opening of the epoxide to give the title compound were carried out as previously described in Examples 9 and 7.
