non-sedating antihistamine drug, Bilastine was described in this manuscript. This competitive synthetic approach involves the convergent synthesis of Bilastine via simple Friedel-Crafts acylation as an alternate for earlier reported Stille and Suzuki couplings. The selectivity in Friedel-Crafts acylation reaction with chloro acetyl chloride on different substituted arenes was studied and employed the best conditions
该手稿描述了新型合成第二代非镇静
抗组胺药Bilastine的努力。这种竞争性的合成方法涉及通过简单的Friedel-Crafts酰化反应进行Bilastine的聚合合成,作为早期报道的Stille和Suzuki偶联的替代方法。研究了
氯代
乙酰氯在不同取代的
芳烃上与Friedel-Crafts进行酰化反应的选择性,并为合成Bilastine提供了最佳条件。进一步的合成方法包括一步将芳基酮脱氧成相应的
烷烃,最后利用适合公斤级合成的简单且经济高效的试剂为Bilastine提供了39%的提高的总收率。
