We describe a general strategy for the aza-Michael addition of nucleophilic heterocycles into β-substituted acrylates using potassium tert-butoxide as catalyst. Demonstrating that the reaction is under thermodynamic control underpins optimization efforts and enables rapid exploration of the substrate scope, with yields ranging from 55% to 94%. We further leverage these lessons in a significantly shortened synthesis of MK-0429, a potent pan-integrin inhibitor previously taken into human clinical trials for the treatment of prostate cancer and osteoporosis.

3(S)-(6-Methoxypyridin-3-yl)-3-{2-oxo-3-[3-(5,6,7,8-tetrahydro-[1,8] -naphthyridin-2-yl)propyl]-imidazolidin-1-yl}propionic acid 6 was identified as a potent and selective antagonist of the αvβ3 receptor. This compound has an excellent in vitro profile (IC50 = 0.08 nM), a significant unbound fraction in human plasma (12%), and good pharmacokinetics in rat, dog, and rhesus monkey. On the basis of the efficacy shown in three in vivo models of bone turnover, the compound was selected for clinical development. To support the ongoing metabolism and safety studies, a novel strategy was employed in which a series of oxidized derivatives of 6 were prepared by exposure of 6 (or the methyl ester) to chemical oxidizing agents. These products proved useful in the identification of active metabolites generated by either in vitro or in vivo metabolism.
Process and intermediates for the preparation of imidazolidinone αv integrin antagonists
-
, (2008/06/13)
A novel process is provided for the preparation of imidazolidinone αvβ3/αvβ5 integrin antagonists, and the useful intermediates obtained therein. These compounds are antagonists of αvβ3/αvβ5 integrin receptors and thus useful for inhibiting bone resorption and treating and preventing osteoporosis. Also disclosed is 3-{2-oxo-3-[3-(5,6,7,8-tetrahydro-[1,8]naphthyridin-2-yl)-propyl]imidazolidin-1-yl}-3(S)-(6-methoxy-pyridin-3-yl)-propionic acid in the form of a hemihydrate.
