Hydrazine hydrate (1:1) → HCID 135991676, compound

Participants

Reaction Steps

In 2 ml of ethanol was dissolved 0.172 g of 3-amino-4,5-diethoxycarbonyl-2-phenyl-6-(tetrazol-1-yl)pyridine, whereto 1 ml of hydrazine monohydrate was added. The mixture was reacted at 90° C. for 2 hours. After 15 ml of ethanol was added, the mixture was cooled. The precipitate was collected by filtration and washed with ethanol. The thus-obtained precipitate was dissolved in 20 ml of hot water, and 0.7 ml of acetic acid was added. The mixture was cooled, and the resulting precipitate was collected by filtration, washed and dried, to give 0.11 g of the title compound as yellow crystals.
