described from 3‐pyridinecarboxaldehyde, thiourea, and ethyl cyanoacetate. Alkylation of 1 with mono‐ and dihaloalkanes under different conditions, provided 2a,b, 3a,b, and 4a‐i. Halogenation of 4g with POCl3 yielded 5 which underwent nucleophilic substitution with amines to give 6a‐g. Fusion of 4a with aromatic and heterocyclic amines at 160°C gave the substitution products 7a‐c. Some of the compounds

The serine/threonine specific protein kinase B-Raf is part of the MAPK pathway and is an interesting oncology target. We have identified thieno[2,3-d]pyrimidines as a core scaffold of small molecule B-Raf inhibitors. The SAR of analogs in this series will be described. (C) 2011 Published by Elsevier Ltd.
