Versuchsvorschrift

Entry 14: 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. According to Method C4, 2-methoxy-5-(trifluoromethyl)aniline was reacted with phosgene followed by 4-(2-carbamoyl-4-pyridyloxy)aniline to afford the urea.
