Acetic Anhydride → 2-Acetoxymethyl-5-methoxypyridine
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | 5-Methoxy-2-methyl-1-oxo-1lambda~5~-pyridine | HCID 12214019 | — |

Reaction Steps
The crude N-oxide product obtained above (13.5 g.) was then placed in acetic anhydride (100 ml.) and heated on a steam bath for a period of three hours. The excess anhydride was thereafter removed by means of distillation and the liquid residue so obtained was fractionally distilled to give pure 2-acetoxymethyl-5-methoxypyridine (yield, 6.6 g.), b.p. 148°-150° C./12 mm. Hg. This particular product was then hydrolyzed by heating same on a steam bath while in concentrated hydrochloric acid for a period of four hours. Evaporation of the resulting reaction solution then gave crude 2-hydroxymethyl-5-methoxypyridine as the residue.
