i have been working on a Michael addition experiment.
And i have difficulty in finding the structure of its product
can someone help me please
the name of my product is
1-Phenyl-3-phenylaminopyrrolidine-2, 5-dione
thanks a lot

What is the structure of pyrrolidine? Of pyrrolidine-2,5-dione? ...

Or alternatively, what reactions did you carry out, perhaps we can build the structure up that way?

[glock17]

the experiment consist of two step
first prepare Maleanilic acid by the following reactant

maleic anhydride (3g, 30 mmol) and aniline (3g, 32 mmol) in glacial
acetic acid (15 ml) for 30 min. at room temperature

second step:
Reflux the mixture of aniline (1g, 11 mmol), crude maleanilic acid (A) from the above
preparation (2g, 10 mmol) and glacial acetic acid (10 ml) for 30 min.
then 1-Phenyl-3-phenylaminopyrrolidine-2, 5-dione is obtained

i think i come up a structure according to your method

and by adding carbonly group to the two carbon near to the nirtogen ring
thx i think i got it~
