Procedure
A mixture of 2,4-dichloro-5-methylsulfonylbenzoic acid (15 g.; 0.055 mole) and furfurylamine (30 ml.) is heated in an oil bath at 125° C. under an atmosphere of nitrogen for 3 hours then poured into cold, dilute hydrochloric acid (200 ml.) to precipitate 17.6 g., (98%) of 2-furfurylamino-4-chloro-5-methylsulfonylbenzoic acid, m.p. 204° C. (dec.) after recrystallization from nitromethane (200 ml.).
