Dicyclohexylcarbodiimide → 2-Phenoxy-benzoic acid 3,5-bis-trifluoromethyl-benzyl ester

Participants

Reaction Steps

To a solution of 118 mg (0.55 mmol) 2-phenoxybenzoic acid and 122 mg (0.50 mmol) 3,5 bis(trifluoromethyl)benzyl alcohol in 1.5 ml dichloromethane at 0° C. was added a solution of 124 mg (0.60 mmol) 1,3-dicyclohexylcarbodiimide and 7 mg (0.06 mmol) 4-dimethylaminopyridine in 1 ml dichloromethane. The ice bath was removed and stirring was continued at room temperature overnight. The solvent was removed in vacuo and the residue re-dissolved in diethyl ether, filtered and evaporated. The residue was purified by flash chromatography to give 70 mg (32%) of the title compound as white crystals.
