Participants

Reaction Steps

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-isopropyl-piperazine instead of 2-piperazin-1-yl-benzonitrile, to the title compound (6.2 mg, 9.3%) as light yellow oil. MS m/e=457.4 [M+H]+.
