Synthesis of mannish bases derivatives containing aromatic rings were synthesized by the condensation 4-nitrobenzoyl azide  with mannich bases to form (4-nitrophenyl) (piperidin-1-yl) methanone . In the same way 4-nitrobenzoyl azide  treated with substituted aniline to form 4-nitro-N-phenylbenzamide . The purification of these compounds is monitored by T.L.C. The structure of these newly synthesized compounds were characterized by 1H NMR, 13CNMR, Mass, IR, and elemental analysis.
Keywords: Mannich Bases, DMF, Acetone, Substituted Aniline
