실험 절차

Hydrogen chloride gas was bubbled through a suspension of trans-3-hydroxy-L-proline (1.5 g, 11.4 mmol) in 20 ml of freshly distilled MeOH at 0° C. for 30 min. The resulting clear solution was stirred overnight, then concentrated under reduced pressure to afford the title compound as a white solid (1.96 g). Yield 94%.
