Synthesis of Novel Heterocyclic Derivatives Containing Di aze

Chalcones are starting compounds in synthesis of heterocycles containing di nitrogen atoms which named (di aze), an attempt to synthesis of chalcones from acetanilide with aromatic aldehydes such as P-N,N-dimethyl benzaldehyde and P-hydroxy benzaldehyde by Claisen-Schmidt condensation. The resulting chalcones after purification have been converted into substituted pyrazoline and pyrimidine by reaction with hydrazine hydrate,urea,thiourea and guanidine. All these compounds were characterized by Physical and spectral methods such as melting point, FT-IR, H-NMR and C.H.N analysis.
