A series of new urea/thiourea derivatives 3a-j were synthesized by simple addition reaction of functionalized phenyl isocyanates/isothiocyanates 2a-j with N-(5-amino-2-methylphenyl)-4-(3-pyridyl)-2-pyrimidinamine (imatinib intermediate) (1) in the presence of 1,4-dimethyl piperazine (DMPZ) as a base, and another series of new sulfonamide/carbamate derivatives 5a-k were synthesized by reacting 1 with various substituted aromatic sulfonyl chlorides 4a-f and aromatic/aliphatic chloroformates 4g-k in the presence of DMPZ as a base. The title compounds 3a-j and 5a-k were characterized by IR, 1H, 13C NMR and mass spectral data. Antimicrobial, antioxidant and in silico molecular docking studies were made against aromatase.
