実験手順

A solution of 5.24 g (0.02 mole) of 1-benzyl-3-ethoxycarbonyl-4-hydroxyiminopyrrolidine [prepared as described in step (a) above] in 10 ml of toluene was added dropwise to 28 ml of a 3.4M solution of sodium bis(2-methoxyethoxy)aluminum hydride in toluene over a period of 1 hour. The mixture was stirred at room temperature for 1.5 hours and was then heated under reflux for 2 hours. At the end of this time, the reaction mixture was allowed to cool to room temperature, after which ice and water were added to it to form a precipitate, which was removed by filtration. The filtrate was concentrated by evaporation under reduced pressure, and the residue was purified by column chromatography through silica gel using methanol as the eluent, to afford 2.16 g of 3-amino-1-benzyl-4-hydroxymethylpyrrolidine as a brown oil.
