Procedure
Trifluoroacetic acid (5 mL) was added to a solution of tert-butyl 4-[4-({[tert-butyl(diphenyl)silyl]oxy}methyl)-2-oxo-2,3-dihydro-1H-imidazol-1-yl]piperidine-1-carboxylate (550 mg, 1.03 mmol) in dichloromethane (15 mL). After 30 min, the reaction was concentrated to give the title compound.
