piperidine in the key SNAr coupling with 1-fluoro-4-nitrobenzene. Microwave coupling of 4-morphilinoaniline 8 and 4-(piperazine-1-yl)aniline 9 with 2-(2,5-dichloropyrimidine-4-ylamino)-N-methylbenzamide 10, proved to be the most efficacious route to the target analogues 6 and 7. This hybrid methodology reduced the number of synthetic steps, gave enhanced overall yields and increased atom economy through step
蛋白激酶抑制剂CTX-0152960(6,2 - ((5-氯-2 - ((4-吗啉代苯基)氨基)嘧啶-4-基)氨基) - ñ甲基苯甲酰胺),和哌嗪基类似物,CTX-0294885 (7,使用混合流动和微波方法制备了2-((5-氯-2-((4-哌嗪-1-基苯基)氨基)嘧啶-4-基)氨基)-N-甲基苯甲酰胺。使用流动化学的办法避免在密钥S的哌啶的Boc保护的需要Ñ的Ar与1-氟-4-硝基苯耦合。4-吗啉基苯胺8和4-(哌嗪-1-基)苯胺9与2-(2,5-二氯嘧啶-4-基氨基)-N-甲基苯甲酰胺10的微波偶合,被证明是对目标类似物6和7最有效的途径。相对于原始的批处理合成方法,这种混合方法减少了合成步骤的数量,提高了总收率,并通过减少步骤减少了色谱分离的要求,从而提高了原子经济性。
