Procedure

A mixture of (3S)-1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (4.0 g, 0.017 mol) in methylene chloride (10 mL, 0.2 mol) and 4.0 M of hydrogen chloride in 1,4-dioxane (30 mL) was stirred at rt for 2 hours. The volatiles were removed in vacuo to afford the desired product in quantitative yield. The crude product was used in the following step without further purification. LCMS: m/z 166.2 (M+H)+.
