실험 절차

7.26 g (22.3 mmol) (RS)-1-(4-benzyloxy-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid methyl ester is dissolved in 200 ml tetrahydrofuran. After addition of 726 mg palladium 10% on charcoal hydrogenation is performed at RT and normal pressure. After 3 hours, the catalyst is filtered off and the solvent evaporated to yield 6.04 g of crude product (used in the next step without further purification).
