Participants

Reaction Steps

To 1.80 g of 4-[6-(2,3-dimethoxyphenyl)hexyloxy]-3-propylbenzoic acid in 125 mL of methylene chloride cooled at -70° was added 14 mL of 1M boron tribromide in methylene chloride. After 30 minutes at -70° and 5 hours at -20°, the reaction was worked up as in Example 32 and the product was recrystallized from ether-hexane to give 1.12 g, mp 123°-124° of 4-[6-(2,3-dihydroxyphenyl)hexyloxy]-3-propylbenzoic acid.
