HCID 25121015HCID 25121015, compound

Procedure

As described for Example 1f, 1-benzyl-4-[tert-butoxycarbonyl-(2,4-difluoro-benzyl)-amino]-pyrrolidine-2-carboxylic acid (60.0 mg, 0.134 mmol) was converted, using 1-(4-fluoro-phenyl)-piperazine instead of 2-piperazin-1-yl-benzonitrile, to the title compound (7.6 mg, II %) as light yellow oil. MS m/e=509.4 [M+H]+.
