Versuchsvorschrift

The residue obtained by treating, with 4N hydrochloric acid, (2S)-1-[N-(tert-butoxycarbonyl)-L-prolyl]-2-(1-hydroxy-2-phenoxyethyl)pyrrolidine (751 mg) prepared in Example 46-C) was subjected to condensation with (2S)-3-phenyl-2-(1-piperidinyl)propionic acid hydrochloride (500 mg) in the same manner as in Example 48-B) to give 818 mg of the title compound.
