Methods are disclosed for making a compound of formula and intermediates therefor, where R is aryl or heteroaryl, and L is C3_8alkylene, wherein each of R, L, and the illustrated phenyl group are independently optionally substituted with one or more substituents selected from the group consisting of C].6alkyl, Ci.6alkoxy, CF3, CHF2, CH2F, fluoro, and cyano, which methods can avoid the use of iodo-phenyl esters, or aryl alkynes, or both, or, in which synthetic methods at least one of the intermediates is a solid at room temperature that does not require purification by chromatography.
揭示了制备公式化合物及其中间体的方法,其中R是芳基或杂环芳基,L是C3_8烷基,其中R,L和所示苯基中的每一个都可以独立地选择性地被一个或多个来自C].6烷基,Ci.6烷氧基,CF3,CHF2,CH2F,氟和氰的取代基取代。这些方法可以避免使用碘代苯酯或芳基炔烃或两者,或者在合成方法中至少一个中间体在室温下是固体,不需要通过色谱纯化。
