To a solution of tert-butyl 4-methyl-4-methylsulfonyl-piperidine-1-carboxylate (430 mg, 1.550 mmol) in DCM (10 mL) was added TFA (3 mL, 38.94 mmol) and the solution stirred at room temperature for 1 h. The reaction was concentrated and azeotroped twice with DCM to give 4-methyl-4-(methylsulfonyl)piperidine as a sticky oil that was used in next step without further purification. MS (ES+) 178.0.
