Procedure

Entry 109: 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 A2, Step 4 using DMAC in place of DMF to give 3-(2-carbamoyl-4-pyridyloxy)aniline. 3-Amino-2-methoxyquinoline was reacted with 3-(2-carbamoyl-4-pyridyloxy)aniline according to Method C5 to afford the urea.
