Benzoic Acid → 3,5-Dichloro-4-(3-benzoyloxypropyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene

Participants

Reaction Steps

First, 11.1 g of 1-(3-bromopropyloxy)-2,6-dichloro-4-(3,3-dichloro-2-propenyloxy)benzene, 3.31 g of benzoic acid, and 50 ml of N,N-dimethylformamide were placed in a reaction vessel, to which 3.90 g of potassium carbonate was added. After stirring at room temperature for 24 hours, the reaction mixture was poured into water, and extracted twice with diethyl ether. The diethyl ether layers were combined, washed with water, dried over anhydrous magnesium sulfate, and concentrated to give a crude product. this crude product was subjected to silica gel chromatography, which afforded 11.6 g (yield, 95%) of 3,5-dichloro-4-(3-benzoyloxypropyloxy)-1-(3,3-dichloro-2-propenyloxy)benzene.
