摘要:
A series of heterobiaryl amides was designed and synthesized as novel mGluR5 antagonists. The synthesis using palladium catalyzed Suzuki-Miyaura cross-coupling reactions provided art array of compounds with a range of in vitro activities. In particular, compound 9e, 4( 3,5-difluorophenyl)-N-(6-methylpyridin-1-yl)picolinamide, exhibited nanomolar affinity at the mGluR5 and will serve as a template for future drug design.
