Abstract: The present invention is related to oxindole derivatives of structure (I), compositions containing the same, and methods of use and manufacture of the same. Such compounds generally are useful pharmacologically as agents in those disease states alleviated by the alteration of mitogen activated signaling pathways in general, and in particular in the inhibition or antagonism of protein kinases, which pathologically involve aberrant cellular proliferation. Such disease states include tumor growth, restenosis, atherosclerosis, pain and thrombosis. In particular, the present invention relates to a series of substituted oxindole compounds, which exhibit Trk family protein tyrosine kinase inhibition, and which are useful in cancer therapy and chronic pain indications.

Abstract: The present invention relates to a method of making a compound of the formula wherein X1, X2 and R3—R4 are as defined herein. The method includes reacting a compound of the formula with an amine of formula 3 (HNR3R4) in the presence of a Lewis Acid and a non-nucleophilic base. The 2,4-diamino pyrimidine moiety is a common component in a variety of biologically active drug-like molecules and pyrimidine derivatives have been found to be useful in the treatment of abnormal cell growth, such as cancer, in mammals.
