3-(Benzimidazol-2-yl)-pyridine-2-one-based ATP competitive inhibitors of Insulin-like Growth Factor 1 Kinase (IGF-IR) were optimized for reduced Cyp3A4 inhibition and improved oral exposure. The use of malonate as methyl anion synthon via SNAr reaction and double decarboxylation under mild conditions is demonstrated. (c) 2008 Elsevier Ltd. All rights reserved.
