Versuchsvorschrift

t-Butyl (3R,4R)-3-benzyloxycarbonylamino-4-hydroxypyrrolidine-1-carboxylate (16 g) was dissolved in chloroform (143 mL), followed by addition of a solution (72 mL) of 4 M HCl in 1,4-dioxane, and the mixture was stirred overnight at room temperature. The solvent was evaporated under reduced pressure to obtain benzyl ((3R,4R)-4-hydroxypyrrolidin-3-yl)carbamate mono hydrochloride. This compound was used in the subsequent step without purification.
