Reaction Steps
Entry 107: 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 4-aminophenol according to Method A2, Step 4 using DMAC in place of DMF to give 4-(2-carbamoyl-4-pyridyloxy)aniline. 4-(2-Carbamoyl-4-pyridyloxy)aniline was reacted with 4-(2-(N-isopropylcarbamoyl)-4-pyridyloxy)aniline according to Method C5 to afford the urea.
