Synthesis and anticancer assessment of some new 2-amino-3-cyanopyridine derivatives
The 2-Aminonicotinonitrile derivative was reacted with different bi-functional reagents such as formamide, thiourea, acetic anhydride, and phthalic anhydride under optimized conditions to give pyrimidine, thiourea, acetamide, and isoindoline derivatives, respectively, When it was treated with active methylene reagents as malononitrile, phenacyl bromide, and ethyl bromoacetate under varied experimental modulation, it afforded 1, 8-naphthyridine, ethyl, and methylamino nicotinonitrile derivatives, respectively. Also, it was reacted with p-toluene sulfonyl chloride, chloroacetyl chloride, and benzoyl chloride to give sulfonamide, 2-chloro-N-acetamide, and benzamide derivatives, respectively. Likewise, it was reacted with diethyl malonate, ethyl cyanoacetate, and cyano acetic acid to give ethylpropanoate, naphthyridine, and cyano acetamide derivatives, respectively. However, treatment of ethylpropanoate and cyano acetamide derivatives with hydrazine hydrate gave pyrazole and 5-amino-pyrazole nicotinonitrile derivatives, respectively. In addition, it was reacted with p-anisaldehyde, phenyl isocyanate, and triethyl orthoformate to give benzylamino nicotinonitrile, phenyl urea, and N-formamide derivatives, respectively. Furthermore, it was reacted with nitrous acid then coupled with aniline; it was also reacted with isatine and 1,3- dibromo propane to give oxoindoline derivative, and the dimer. Elemental analyses, together with spectroscopic data including IR, H-1-NMR in addition to C-13-NMR and mass spectra submit proofs for the chemical structures for all compounds. [GRAPHICS]
