Procedure
Entry 99: 4-Chloropyridine-2-carbonyl chloride was reacted with ethylamine according to Method A2, Step 3b. The resulting 4-chloro-N-ethyl-2-pyridinecarboxamide was reacted with 4-aminophenol according to Method A2, Step 4 to give 4-(2-(N-ethylcarbamoyl)-4-pyridyloxy)aniline. 4-Chloro-2-methoxy-5-(trifluoromethyl)aniline was synthesized according to Method A7. 4-Chloro-2-methoxy-5-(trifluoromethyl)aniline was converted into 4-chloro-2-methoxy-5-(trifluoromethyl)phenyl isocyanate according to Method B1. According to Method C1a, 4-chloro-2-methoxy-5-(trifluoromethyl)phenyl isocyanate was reacted with 4-(2-(N-ethylcarbamoyl)-4-pyridyloxy)aniline to afford the urea.
