反応手順
Two moles of phthalic anhydride (296 g.) and one mole of oxalic dihydrazide (118 g.) in 500 ml. N-methyl-2-pyrrolidone and 500 ml. toluene were heated at reflux until two moles of water were removed (about two hours). The mixture was diluted with benzene and filtered. After washing with benzene, the white product was dried to constant weight at 50° C. giving an essentially quantitative yield of N,N'-bis(phthalimido)oxamide-N-methyl-2-pyrrolidone 1:2 complex.
