3-Furancarboxylic acid, 5-methyl-2-phenyl-, ethyl ester → 5-Methyl-2-phenylfuran-3-carboxylic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3-Furancarboxylic acid, 5-methyl-2-phenyl-, ethyl ester | HCID 10059727 | — |
| Solvent | Ethanol | HCID 702 | — |
| Solvent | Sodium Hydroxide | HCID 14798 | — |
| Product | 5-Methyl-2-phenylfuran-3-carboxylic acid | HCID 761020 | — |
Reaction Steps
Saponification of 0.5 g of the ester was accomplished by refluxing 12 hours in 10 ml of 25% aqueous sodium hydroxide and 5 ml of ethanol. Acidification precipitated the crude acid, which was recrystallized from water-ethanol to give 5-methyl-2-phenyl-3-furoic acid, mp 146°-147.5° C.
