0.6 g of tert-butyl cis-4-(4-methoxycarbonylcyclohexyloxy)benzoate (1.79 mmol, 1 eq.) is placed in 2.5 mL of dichloromethane. The reaction medium is cooled to a temperature of 4° C. with stirring in an ice bath. 1 mL of trifluoroacetic acid (13.46 mmol, 7.5 eq.) is added and the ice bath is removed. After stirring for 5 hours at room temperature, the medium is concentrated, taken up in diethyl ether, drained and filtered to give 0.30 g of cis-4-(4-methoxycarbonylcyclohexyloxy)benzoic acid. M+H+=279.
