FIELD: organic chemistry, chemical technology, medicine.
SUBSTANCE: invention relates to a method for preparing 1-isonicotinyl-2-D-glucosyl hydrazone. In the glucosylation reaction of isonicotinic acid hydrazide the method involves using anionite AN 31 GS as a catalyst of the enhanced effectiveness, and using 95-96.5% ethanol or 85-90% isopropanol as the reaction medium. At the final stage the method involves sorption of contaminating impurities with activated carbon followed by drying the end product in nitrogen atmosphere.
EFFECT: improved preparing method.
