Reaktionsschritte
In an alternate method, one mole N,N'-bis(phthalimido)-oxamide (378 g.) prepared according to the method of Example 1 and excess N-methyl-2-pyrrolidone (198 g.) in two liters toluene were heated at 70° C. After cooling, the complex was filtered, washed and dried at 50° C. N,N'-bis(phthalimido)oxamide-N-methyl-2-pyrrolidone 1:2 complex was obtained in 96% yield.
