Reaktionsschritte

To a solution of 2-oxo-pyrrolidine-1-carboxylic acid tert-butyl ester (7.03 g, 38 mmol) in THF (130 mL) was added phenylmagnesium bromide (1.0 M solution, 50 mL) at −78° C. After stirring for 2 hour at −78° C., HCl (2 M, 35 mL) was added to quench the reaction, which was then warmed to room temperature and the aqueous layer was extracted with EtOAc (2×100 mL). The combined organics were washed with brine (50 mL) and dried over Na2SO4, filtered and concentrated under reduced pressure to afford 9.56 g (96% yield) of the desired product.
