Procedure

To a stirred solution of biphenyl-2-ylcarbamic acid 1-(2-{[3-(4-(1,3-dioxolan-2-yl)phenylcarbamoyl)phenyl]methylcarbamoyl}ethyl)piperidin-4-yl ester (345 mg containing some solvent residue, ca. 0.500 mmol) in acetonitrile (2.00 mL) at room temperature was added aqueous hydrochloric acid (1 N, 2.00 mL). The reaction mixture was stirred at room temperature for 3 h. LC-MS (Method 10-90) showed product was present (Rt 3.45 min; m/z 605.0 [M+H]+. Saturated aqueous sodium bicarbonate solution was added and the layers were separated. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to give the title compound, which was used in the next reaction without further purification.
