  • Publication number: 20260159522
    Abstract: The invention relates to a novel process for the preparation of chiral pyrrolo triazole alcohols of the formula I wherein X is a halogen atom, n is an integer of 1, 2 or 3 and wherein the spiral bond “” stands for “” or for “” or mixtures of the enantiomers. The chiral pyrrolo triazole alcohols of the formula I are versatile intermediates for the preparation of compounds that have the potential to serve as active pharmaceutical ingredients in drugs.

  • Publication number: 20250051351
    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 2and a highly chemoselective Pt/V/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.
