2-(4-Fluorobenzyl)malonic acid → 3-(4-Fluorophenyl)propionic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-(4-Fluorobenzyl)malonic acid | HCID 15120643 | — |
| Solvent | Diethyl Ether | HCID 3283 | — |
| Product | 3-(4-Fluorophenyl)propionic acid | HCID 136302 | — |
Reaction Steps
The 4-fluorobenzylmalonic acid is heated to 170° to 175° for 1.5 hours. After cooling, the reaction product is stirred with a little diethyl ether. 41.6 g of 3-(4-fluorophenyl)propionic acid of m.p. 85° to 88° [from ethyl acetate/petroleum ether (1:4)] thereby crystallize out.
