  • Publication number: 20230028651
    Abstract: A manufacturing process to a bis-mesylate salt 1b of the pan-RAF inhibitor 4-amino-n-(1-((3-chloro-2-fluorophenyl)amino)-6-methylisoquinolin-5-yl)thieno[3,2-d]pyrimidine-7-carboxamide. The process features a number of efficient key reactions, including a robust and scalable Pd-catalyzed carbonylation reaction to generate thienopyrimidine 2 and a highly chemoselective PtN/C-catalyzed nitro group reduction to access penultimate intermediate 7. The final amide coupling of 7 and 2 was accomplished by a mild and safe protocol employing N,N,N?,N?-tetramethylchloroformamidinium hexafluorophosphate (TCFH) as the coupling reagent, to produce a 1:1 adduct of the freebase and THF. The adduct afforded compound 1b with excellent yield, purity, and form stability on a multikilogram production scale after reaction with MsOH and recrystallization. The methods are able to produce a compound having upwards of 95% purity.

  • Publication number: 20220297096
    Abstract: The present invention relates to a novel process for the preparation of a nitrogen containing biopolymer-based catalyst and to the novel nitrogen containing biopolymer-based catalysts obtainable by this process. In particular, the invention relates to a novel nitrogen containing biopolymer-based catalyst comprising metal particles and at least one nitrogen containing carbon layer. The invention also relates to the use of a nitrogen containing biopolymer-based catalyst in a hydrogenation process, preferably in a process for hydrogenation of nitroarenes, nitriles or imines; in a reductive dehalogenation process of C—X bonds, wherein X is Cl, Br or I, preferably in a process for dehalogenation of organohalides or in a process for deuterium labelling of arenes via dehalogenation of organohalides; or in an oxidation process.
