A synthesis approach providing an early ring attachment via a bromination to compound l-l yielding compound II-Il, whereby a final product such as AA can be synthesized. In particular, the 2,4-difluorophenyl-containing sidechain is attached before creation of the additional ring Q.
一种合成方法,通过对化合物l-l进行
溴化反应提供早期的环附加,得到化合物II-Il,从而可以合成最终产物
AA。特别地,在创建额外的环Q之前,附加了含有2,4-二
氟苯基侧链。
