Versuchsvorschrift

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.
