chloroacetonitrile. These compounds were conveniently converted into novel pyrido[4′,5′:4,5]thieno[3,2-d]pyrimidines. Also, 2,3-dihydro-1,3,4-thiadiazole was synthesized from hydrazonoyl halides and 2-benzofuran-2-yl-3-(phenylamino)-3-thioxopropanenitrile. The structures of the products have been elucidated by elemental analyses, spectral data studies, and alternative syntheses whenever possible. The
Discovery of [5-Amino-1-(2-methyl-3<i>H</i>-benzimidazol-5-yl)pyrazol-4-yl]-(1<i>H</i>-indol-2-yl)methanone (CH5183284/Debio 1347), An Orally Available and Selective Fibroblast Growth Factor Receptor (FGFR) Inhibitor
The fibroblastgrowthfactorreceptor (FGFR) family of receptor tyrosine kinases regulates multiple biological processes, such as cell proliferation, migration, apoptosis, and differentiation. Various genetic alterations that drive activation of the receptors and the pathway are associated with tumor growth and survival; therefore, the FGFR family represents an attractive therapeutic target for treating

1a–1e and alkenes 2a–2g with cerium(IV) ammonium nitrate (CAN) in ether solvents was investigated (Tables 1 and 2). In the optimization study, 1,3‐dioxolane, 1,4‐dioxane, 1,2‐dimethoxyethane, Et2O, and THF were used as ether‐based solvents, and the latter was found to be the most effective solvent in radical cyclizations mediated by cerium(IV). This system (cerium(IV)/THF) was applied to cyclizations
