We report the synthesis and biological evaluation of aminopyridines substituted with benzoxazole. The SAR of the aminopyridines was explored to improve the inhibitory activity against c-Met and to decrease hERG affinity. These studies led to the discovery of amide 24 which showed good c-Met inhibitory potency, low affinity to hERG and favorable pharmacokinetic properties in rats. (C) 2010 Elsevier Ltd.

from the olefin-bound complex observed during arene borylation to a species containing a bound heteroarene, leading to catalyst deactivation. Studies on the origins of the observed regioselectivity show that borylation occurs distal to N-H bonds due to rapid N-H borylation, creating an unfavorable steric environment for borylation adjacent to these bonds. Computational studies and mechanistic studies show
