Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Trifluoroacetic anhydride | HCID 9845 | — |
| Reactant | 1,4-Dioxane | HCID 31275 | — |
| Reactant | HCID 88186782 | HCID 88186782 | — |
| Solvent | Pyridine | HCID 1049 | — |
| Product | HCID 18317950 | HCID 18317950 | — |
Reaction Steps
0.9 g of the compound obtained in Step B is stirred for 2 hours at ambient temperature in a solution of 10 ml of dioxane, 0.8 ml of pyridine and 0.42 ml of trifluoroacetic anhydride. After evaporating off the solvent, chromatography of the residue on silica gel (dichloromethane/ethyl acetate: 96/4) enables isolation of the expected product, which crystallises in heptane.
