Versuchsvorschrift

To a solution of 0.22 mol. hydrazine in 100 ml. chloroform at -10° C. was added 0.1 mol. of 3,6-dichloro-2-methoxybenzoyl chloride. The mixture was stirred at ambient temperature for 2 hours, filtered, and the filtrate evaporated in vacuo. The residue was crystallized from methanol and water, then recrystallized from chloroform and hexane to obtain the titled product, m.p. 144°-145° C.
