Reaction Steps

112.8 g (0.5 mol) of 4-chloro-3-nitrobenzotrifluoride and 61.1 g (1 mol) of 2-ethanolamine were heated in 50 ml of dimethylformamide at 100° C. for 2 h. The reaction mixture was then concentrated under reduced pressure, and water was added to the residue. The precipitate was filtered off with suction and recrystallized from cyclohexane.
