Reaction Steps

To a solution of tert-butyl 4-(4-bromobenzyl)piperidine-1-carboxylate (780 mg, 2.2 mmol) in CH2Cl2 (15 mmol), was added TFA (0.5 mL) and the mixture was stirred at rt for 1 h. The solvent was removed in vacuo and the residue dissolved into CH2Cl2 (50 mL), washed with NaOH (0.1 M, 10 mL), brine (10 mL), dried over MgSO4 and concentrated to dryness to give the title compound as a beige solid (520 mg, 93%).
