Reaction Steps

The following materials are charged to a reactor: 62.5 g (0.34 mole) 4-aminodiphenylamine, 39 g (0.37 mole) sodium carbonate and 500 ml benzene. To this stirred mixture, under nitrogen, is added a solution of 63.8 (0.35 mole) trichloroacetyl chloride in 100 ml benzene over a thirty minute period. Stirring is continued for another 31/2 hours. The crude product containing sodium chloride by-product is dried to remove solvent. The dried material is washed first with dilute HCl, then distilled water, air dried and the product is recrystallized from a methanol/benzene (1/2) solvent mixture. Melting point and elementary analysis are reported in Table I.
