The Synthesis of a Novel Inhibitor of B-Raf Kinase
摘要:
A scaleable synthetic route to [4,7']bis-isoquinolinyl-1-yl-(2-tert-butyl-pyrimidine-5-yl)amine (1), an inhibitor of B-Raf kinase is described. The key step in the synthesis is the Pd-catalyzed Negishi coupling of 4-bromo-1-chloroisoquinoline with trifluoromethanesulfonic acid isoquinoline-7-yl ester to yield 1-chloro-[4,7']bis-isoquinolinyl. This intermediate is transformed to the desired drug substance in one additional step, by reaction with 2-tert-butyl-5-aminopyrimidine in the presence of NaH. A special focus was put on the finally successful removal of traces of Zn and Pd in the drug substance, which came from the Negishi coupling.
The present invention relates to metal complexes and to electronic devices, in particular organic electroluminescent devices, comprising these metal complexes.

describe the discovery of a novel class of oxadiazole derivatives from which potent and selective CB2 agonist leads were developed. Initial hit 7 was identified from a cannabinoid target-biased library generated by virtual screening of sample collections using a pharmacophore model in combination with a series of physicochemical filters. 7 was demonstrated to be a selective CB2 agonist (CB2 EC50 = 93
