実験手順

To a solution of 2.9 (3R, 4R) and (3S, 4S)-1-benzyl-4-(tert-butoxycarbonylamino-methyl)-pyrrolidine-3-carboxylic acid ethyl ester (8.0 mmol) in 50 ml THF were added 671 mg lithium hydroxide mono hydrate (, 16 mmol) and 0.5 ml water. The solution was stirred at 40° C. and the reaction monitored by TLC. After 72 h the solvent was evaporated, the residue dissolved in dichloromethane, washed with water and brine, dried over Mg sulfate, filtered and evaporated. The residue was crystallized from a dichloromethane/hexane mixture.
