Acetic Anhydride → (3-Methylpyridin-4-yl)methyl acetate
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | 3,4-Dimethylpyridine 1-oxide | HCID 302454 | — |
| Solvent | Water | HCID 962 | — |
| Product | (3-Methylpyridin-4-yl)methyl acetate | HCID 569215 | 30% |
Reaction Steps
The N-oxide was added portionwise to 60 mL of acetic anhydride and the resulting dark orange solution was heated (water-bath) at about 90° C. for 1 h. The excess acetic anhydride was then distilled off under reduced pressure and the material boiling at 90°-120° C./0.1 torr (39.0 g) was collected. Chromatography of this oil (silica gel/ethyl acetate-pet.ether=2:3) afforded pure 4-acetoxymethyl-3-methylpyridine (19.0 g, 30%) as an oil: ir (neat) 1745 cm-1.
