1.6 g of tert-butyl trans-4-(4-methoxycarbonylcyclohexyloxy)benzoate (4.78 mmol, 1 eq.) are placed in dichloromethane. The reaction medium is cooled to a temperature of 4° C. with stirring in an ice bath. 3 mL of trifluoroacetic acid (40.39 mmol, 8.44 eq.) are added and the ice bath is removed. After stirring for 17 hours at room temperature, the medium is concentrated, taken up in diethyl ether and filtered to give 1.0 g of trans-4-(4-methoxycarbonylcyclohexyloxy)benzoic acid.
