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. | Preparation of some benzo[d]thiazole-containing acetohydrazide derivatives
