Procedure
The title compound is prepared from (2-oxopyrrolidin-3-(S)-yl)-carbamic acid tert-butyl ester as described in EXAMPLE 1, Part H using a 2:1 mixture of 5-bromomethyl-2-chloro-quinoline to 7-bromomethyl-2-chloro-quinoline, as prepared in EXAMPLE 15, Part C, in place of 7-bromomethyl-1-chloro-isoquinoline. The crude product mixture is purified by column chromatography eluting with 1% MeOH in 25% EtOAc/CH2Cl2 to afford as the major product the title compound as a beige solid.
