3-Furancarboxylic acid, 2,5-dimethyl-, ethyl ester → 2,5-Dimethyl-3-furoic acid
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3-Furancarboxylic acid, 2,5-dimethyl-, ethyl ester | HCID 141457 | — |
| Solvent | Sodium Hydroxide | HCID 14798 | — |
| Product | 2,5-Dimethyl-3-furoic acid | HCID 69465 | — |
Reaction Steps
Saponification of 0.5 g of the ester was accomplished by refluxing 4 hours in 10 ml of 25% aqueous sodium hydroxide. Acidification precipitated the crude acid, which was recrystallized from water to give 2,5-dimethyl-3-furoic acid as white needles, mp 135.5°-136.0° C.
