Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | m-Chlorophenylhydrazine hydrochloride | HCID 75331 | — |
| Reactant | Methyl atropate | HCID 193334 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | HCID 2766650 | HCID 2766650 | 79.9% |
Reaction Steps
A mixture of 10.5 grams of the atropic acid, methyl ester, 9.1 grams 3-chlorophenylhydrazine hydrochloride, and 200 ml. methanol was refluxed overnight. The reaction product mixture was washed up in the usual manner to yield 11 grams of crude 1-(3-chlorophenyl)-4-phenyl-3-pyrazolin-5-one. A sample recrystallized from methanol had a melting point of about 211°-212° C.
