Procedure

Ten grams of 3,5-dinitro-4-chloro-o-toluic acid is warmed on a water bath with 9.2 grams of phosphorus pentachloride and 30 ml. of benzene. After the solids dissolve, the benzene is distilled and the phosphorus oxychloride is removed under reduced pressure. The desired product as a residual oil solidifies on chilling.
