Tóm tắt

Four benzo[d]thiazole-containing acetohydrazide derivatives 1c, 2c, 3e,
and 4e were prepared via condensation reaction of esters and hydrazine hydrate up
to 89% yield. These processes involved in some modification of some known
compounds in ether synthesis and acetylation of amino groups. Structures of these
derivatives were elucidated by IR, NMR and MS analysis that referred a strong
agreement between spectral data and structures
