Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethanol | HCID 702 | — |
| Reactant | Sulfuric Acid | HCID 1118 | — |
| Reactant | 5-Nitrosalicylic acid | HCID 7318 | — |
| Product | HCID 12512105 | HCID 12512105 | 85% |
Reaction Steps
To a solution of 5-nitrosalicylic acid (10.8 g) in ethanol (100 ml) was added concentrated sulfuric acid (92.0 g) at room temperature and the mixture was heated under reflux for 7.5 hours. After neutralization with aqueous sodium hydroxide, the reaction mixture was extracted with ethyl acetate. The extractant was washed with saturated aqueous sodium hydrogencarbonate, 0.5M hydrochloric acid and brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and the filtrate concentrated in vacuo to give the desired compound (10.7 g, yield 85%) as a yellow solid.
