Reaction Steps
To a solution of 1.08 g hydrazine in 10 ml 5N hydrochloric acid was added 1.45 g benzoylacetonitrile (prepared according to the procedure of Example 2), under stirring. The mixture was refluxed for 3 hrs. After cooling, the solution was neutralized with Na2CO3. The yellow precipitate was filtrated, washed with H2O, and dried to get 2.1 g 1,3-diphenyl-5-aminopyrazole.
