반응 단계
Two moles of phthalic anhydride (296 g.) and one mole of oxalic dihydrazide (118 g.) in 500 ml. dimethyl sulfoxide and 750 ml. toluene were heated at reflux until two moles of water were removed (about 2 hours). The mixture was cooled 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 #-# dimethyl sulfoxide 1:2 complex.
