Participants

Reaction Steps

Trifluoroactic acid (4 mL, 51.92 mmol) was added to a solution of tert-butyl 3,3-dimethyl-4-oxopiperidine-1-carboxylate (2.0588 g, 9.06 mmol) in dichloromethane (12 mL). The reaction was stirred at RT for 2 h and the solution was concentrated to remove the solvent. The residue as the product was directly used in the next step without further purification. m/z 128.
