Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Methanol | HCID 887 | — |
| Reactant | 5,5-Dimethylpyrrolidin-2-one | HCID 11126210 | — |
| Product | 1-Methyl-2-Oxy-5,5-Dimethyl Pyrrolidine | HCID 444570 | 86% |
Reaction Steps
A solution of 113 g (1 mole) of 5,5-dimethylpyrrolid-2-one and 96 g (3 moles) of methanol was vaporized, and passed over an alumina catalyst at 400° C. Working up the gas mixture in a conventional manner to obtain 1,5,5-trimethylpyrrolid-2-one gives this compound in about 86% yield; boiling point: 236°-238° C.
