Conditions
- Temperature
- 140 °C
Procedure
Equimolar amounts of N-allyl, N-methyl, propylene diamine prepared as described above and Dimethyl Itaconate are charged to a reaction vessel and heated slowly with agitation to 130°-150° C. After the exotherm subsides, the reaction mixture is maintained at 140° C. for 3 hours. The reaction product 1-(N-allyl, N-methyl aminopropyl)-4-carbomethoxy pyrrolidone is isolated by distillation.
