Abstract

The regioselective synthesis of compound 3, a potent Src kinase inhibitor is described. A key step in this synthesis is the regio­selective thermal rearrangement of a substituted benzocyclobutene to provide a 2,3,6,7-tetrasubstituted naphthalene. An efficient route to the uniquely substituted benzocyclobutene is reported.
