Reaction Steps
The title compound is prepared by alkylation of the (RS)-1-(4-hydroxyphenyl)-5-oxo-pyrrolidine-3-carboxylic acid methyl ester with 2,3,4-trifluorobenzyl bromide giving the (RS)-5-oxo-1-[4-(2,3,4-trifluoro-benzyloxy)-phenyl]-pyrrolidine-3-carboxylic acid methyl ester as a white solid (94% of theory) which, thereupon, by treatment with methylamine in ethanol at 50° C. yields the (RS)-5-oxo-1-[4-(2,3,4-trifluoro-benzyloxy)-phenyl]-pyrrolidine-3-carboxylic acid methylamide. Yield: 99% of theory as a white solid; MS: m/e=379 (M+H)+.
