Synthesis, Crystal Structure and Antitumour Activity of 3-Amino-4-Morpholino-1H-Indazol-1-yl(3-Fluorophenyl)Methanone

3-Amino-4-morpholino-1H-indazol-1-yl(3-fluorophenyl)methanone was synthesised by condensation of 3-fluorobenzoic acid with 4-morpholino-1H-indazol-3-amine, which was prepared from 2,6-difluorobenzonitrile by amination with morpholine and then cyclisation with hydrazine hydrate. The molecular structure was tested by single crystal X-ray diffraction. Preliminary biological tests showed that the compound possesses distinct inhibition on the proliferation of A549, BGC-823 and HepG-2 cancer cell lines.
