Novel processes are disclosed for manufacture of N-(3-(5-(4-chlorophenyl)-l H-pyrrolo[2,3-b]pyridine-3-carbonyl)-2,4-difluorophenyl)propane-1-sulfonamide (I), wherein no protection-deprotection sequences or halogenation steps are required and use of palladium catalysts is minimized.
本发明公开了制造 N-(3-(5-(4-
氯苯基)-l H-
吡咯并[2,3-b]
吡啶-3-羰基)-2,4-二
氟苯基)
丙烷-1-磺酰胺 (I) 的新工艺,其中不需要保护-保护序列或卤化步骤,并最大限度地减少了
钯催化剂的使用。
