Hydrazine hydrate (1:1) → HCID 23458501, compound

Participants

Reaction Steps

5.5 g (26.9 millimoles) of cis-2-(p-toluoyl)-cyclopropanecarboxylic acid, 1.5 g (30.0 millimoles) of hydrazine hydrate and 100 ml of ethanol are refluxed for 6 hours. The mixture is then concentrated and the residue is recrystallized from ethyl acetate. 4.3 g (80% of theory) of 2-(p-tolyl)-3,4-diaza-bicyclo[4.1.0]-hept-2-en-5-one are obtained as colorless crystals of melting point 162°-163.5° C.
