Reaction Conditions

Reaction Steps

Hydrogen chloride gas was bubbled through a suspension of 3-hydroxy-piperidine-2-carboxylic acid (0.54 g, 0.370 mol) in MeOH (100 mL) cooled to 0° C. for 10 min. The resulting clear solution was stirred at rt for 4 h, then evaporated carefully under reduced pressure (white precipitates formed during the concentration). The resulting white solid was dried overnight under vacuum to afford 0.86 g of the title compound as an off-white powder.
