Two new syntheses have been developed for the preparation of substituted pyrido[2,3,4-kl]acridines. The first synthesis involves a Skraup reaction and a nitrene insertion whereas the second includes a new pyridine ring synthesis starting from a 1-amino group on acridine and taking advantage of the active 9-position of the latter heterocycle.
