Abstract
Biologically active substances having labile aryl groups can be converted to the corresponding aryl amine derivatives. The biologically active substances are reacted with a diazonium compound which optionally can be linked to a solid, inorganic carrier such as porous glass beads for ease of purification. The diazo reaction product is then reductively cleaved with a chemical reducing agent such as with hydrosulfite to yield the desired amine derivative. A preferred class of biologically active substances used herein is the catecholamines.
