Dicyclohexylcarbodiimide → Cyclohexane-1,4-dicarboxylic acid 1-[4-(11-acryloyloxy-undecyl)phenyl]ester 4-(4-hexylphenyl)ester

Participants

Reaction Steps

2.5 g of N,N′-dicyclohexyl carbodiimide was added to a mixture of 2.0 g of 4-(11-acryloyloxyundecyl)phenol (G), 1.1 g of hexylphenol (E), 1.03 g of trans-cyclohexane-1,4-dicarboxylic acid (F), 0.15 g of 4-N,N-dimethylaminopyridine and 50 ml of dichloromethane, cooled in an ice bath and stirred under a nitrogen atmosphere. The mixture was stirred overnight at room temperature. 0.93 g of cyclohexane-1,4-dicarboxylic acid 1-[4-(11-acryloyloxy-undecyl)phenyl]ester 4-(4-hexylphenyl)ester (6, 25%) was obtained as a white powder after evaporation, and separation by chromatography using silica gel and dichloromethane/petroleum ether 97/3 as eluent.
