Trifluoroacetic acid (6 mL) was added to a solution of N-tert-butoxycarbonyl-4-(2-chloro-5-methylphenoxy)piperidine (A, 489 mg) in dichloromethane (20 mL) at room temperature. After stirring at room temperature for 30 min, the reaction mixture was evaporated in vacuo. The residue was partitioned between chloroform and saturated sodium hydrogen carbonate. The organic layer was dried over anhydrous sodium sulfate and then concentrated in vacuo to give the titled compound as yellow crystals, which was used in the next reaction without her purification.
