Procedure

The acid chloride (16.23 g.) prepared from 3-amino-5-(N-methylacetamido)-2,4,6-triiodobenzoic acid and thionyl chloride was interacted with 60 ml. of dimethylamine (40% in water), 20 ml. of 35% aqueous sodium hydroxide and 30 ml. of water. The product was isolated and recrystallized from isopropyl alcohol to give 3-amino-2,4,6-triiodo-5-(N-methylacetamido)-N,N-dimethylbenzamide as a pale yellow solid, m.p. 235°-240° C.
