An acid and base-stable, nucleophile-resistant protecting group for primary amines and α-amino acids is described which has been used in a synthesis of the title compound.
The invention relates to novel 1-pyridin-4-yl urea derivatives and related compounds and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of the compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as neurohormonal antagonists.

The title compound has been synthesized from 1,3-cyclohexadiene, by a route involving stereo- and regioselective palladium- catalyzed acetoxy chlorination. A key step is the homologation of a nitrile into an α-aminonitrile by the Moinet reaction11.
