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 4-nitrobenzyl bromide in place of 7-bromomethyl-1-chloro-isoquinoline. The crude product is purified by column chromatography eluting with a gradient of 10% EtOAc/CH2Cl2 to 25% EtOAc/CH2Cl2 to afford the title compound as a yellow solid.
