Procedure

Trifluoroacetic acid (0.5 mL) was added to a solution of 1-(1-t-butoxycarbonylpiperidin-4-yl)imidazolidin-2-one (30 mg, 0.11 mmol) in dichloromethane (2 mL) and the reaction stirred at room temperature for 5 h. The reaction was concentrated in vacuo to give the title compound as its trifluoroacetic acid salt (18 mg).
