Reflux a mixture of 11.97 g (0.07 mole) of diglycolic acid dichloride and 28.84 g (0.14 mole) of 3-trifluoromethyl-4-nitroaniline in 250 ml of benzene for 1 hour. Isolate the solid product of this example by filtration and obtain analytically pure material by recrystallization from benzene-methanol followed by crystallizatin from pure methanol, mp 137°-138° C.
