Procedure

Entry 44: 4-Chloropyridine-2-carbonyl chloride HCl salt was reacted with ammonia according to Method A2, Step 3b to form 4-chloro-2-pyridinecarboxamide. 4-Chloro-2-pyridinecarboxamide was reacted with 3-aminophenol according to Method A1, Step 4 to form 3-(2-carbamoyl-4-pyridyloxy)aniline. According to Method C1a, 4-chloro-3-(trifluoromethylphenyl isocyanate was reacted with 3-(2-carbamoyl-4-pyridyloxy)aniline to afford the urea.
