Regioselective synthesis of new biheterocyclic triazepines

Condensation of dihaloalkanes to 1,2,4-triazepine 1a in the Phase Transfer Catalysis (P.T.C.) conditions provides efficient and facile access to biheterocyclic triazepines with high regioselectivity. In the same conditions, the triazepinone 1b has been found to degradate after alkylation to give pyrazoles.
