実験手順

A mixture of 31.8 gm. (0.129 mole) of 2-chloro-3,5-dinitrobenzamide and 50 ml. of phosphorous oxychloride is heated under reflux for one hour. The excess phosphorous oxychloride is removed by distillation under reduced pressure. To the residue is cautiously added ice water. The light yellow-green solid is removed by filtration and washed with water. There is obtained 28.0 g. (95%) of material melting at 139°-41° .
