Abstract

The Letter describes a facile approach to 7, 8-dihydro [1, 2, 4] triazol [1, 5-c] pyrimidin-5-yl amines, a novel class of potent inhibitors of vascular endothelial growth factor receptor II (VEGFR-2). The synthetic sequence is centered around preparation of the key 3 (5)- cyanomethyl-1, 2, 4-triazole intermediates and their Knoevenagel condensation with aromatic aldehydes. A subsequent three-step conversion of Knoevenagel adducts ...
