Yield: 80%

Reaction Conditions:

in ethanol for 2 h;Reflux;

Steps:

General procedure for preparing 5-amino-1-phenyl-1H-pyrazole-4-carbonitriles (10a-c)
General procedure: A mixture of the appropriate phenylhydrazine (0.001 mol)and 10 mL of ethanol was stirred and allowed to reflux.Then, 2-(ethoxymethylene)malononitrile (0.001 mol) dissolvedin 10 mL of ethanol was slowly added. The reactionmixture was refluxed for 2 h. The reaction mixture waspoured into 50 mL of ice-cold water. The precipitate wascollected by filtration and washed with water to provide10a-c in 61-80% yield.
