The synthesis of water soluble hydrochlorides of indazole derivatives 1b, 8 and 9 is described. By treating of 2,5-dinitroindazole with thiomorpholine 3-thiomorpholino-5-nitroindazole (10) and 3,5-dinitroindazole (11) in the form of the molecular compound 11a are obtained. The known indazole derivatives 1 and 7 as well as the newly synthesized(More)
The nucleophilic substitution of hydrogen to synthesize the sulphonyl indazole derivatives 9-16 is described. The structures of the substitution products are discussed using H-NMR spectra. Chemical structural proof was given by steric hindrance observed in the process of chorination of 9-16. The compounds 3, 4, 7, 8, 14, and 16 are studied to find an(More)
