Heterocycles from 2-Aminopyridine and Derivatives of 3-Methylbenzofuran-2-carboxylic Acid.

-The reaction of the 3bromomethylbenzofuran (IV) with aminopyridine (V) gives, besides the expected pyridinium bromide (VI), the pyridyl amine (VII). The latter does not cyclize to a diazepine derivative under various conditions. However, a similar diazepine (XI) can be obtained from the pyridyl amide (X). -(JACKSON, Y.
