Heterocyclic compounds were prepared from Schiff bases triester derivatives, the first step was included, p- aminobenzoic acids convert to p-amino benzoyl chloride in the presence of thionyl chloride then glycerol was added to form triesters compound A. second step reaction of triester product with the 4-nitrobenzaldehyde, and 3-amino benzaldehyde to produce M1, and M2. The third step. Involve reacted Schiff bases triester derivatives to give heterocyclic compounds M1S, M1A, M2P, and M2K. The structure of all compounds is monitored by (TLC), and identified by many techniques 1HNMR, FT-IR, and melting point.
