A six-step synthetic route from 4-chloro-2-methylaniline to 5-chloro-2-(cyclobut-1-en-1-yl)-3-(trifluoromethyl)-1H-indole (1) has been reported. Compound 1a is a key impurity of reverse transcriptase inhibitor efavirenz, an important anti-HIV/AIDS drug. Synthetic challenges, dead ends, and detours are discussed.
已经报道了从4-氯-2-甲基苯胺到5-氯-2-(环丁-1-烯-1-基)-3-(三氟甲基)-1 H-吲哚(1)的六步合成路线。化合物1a是逆转录酶抑制剂依非韦伦的重要杂质,依非韦伦是一种重要的抗HIV / AIDS药物。讨论了合成挑战,死胡同和绕道而行。
