Vinyl azides act as NH+2 equivalents in reaction with aromatic or heteroaromatic lithium derivatives thus providing a direct method for amination of such compounds.
The compounds are 3-(3-(3-substituted amino-2-hydroxypropoxy)phenyl)-6-hydrazino pyridazines which have .beta.-adrenergic blocking and vasodilator activity.
