2-Methoxy-4-(1-Boc-4-piperidyloxy)benzoic acid (0.79 g, 2.24 mmol) was dissolved in ethyl acetate (15 ml). The solution was cooled in ice and saturated with HCl gas, then stirred 30 min in the cold. The mixture was evaporated in vacuo and the residue concentrated from ether three times to give 2-methoxy-4-(4-piperidyloxy)benzoic acid.
