Product Name:Olverembatinib
CAS Number:1257628-77-5
Molecular formula:C29H27F3N6O
Molecular Weight:532.56

In a recent patent, the synthesis of olverembatinib began with a Sonogashira coupling reaction of commercially available alkyne 24.1 with pyridinium bromide 24.2 to afford ester 24.3 in 98% yield. The N-Boc group of carbonate 24.3 was cleaved by refluxing in a mixture of MeOH and water to afford pyrazole 24.4 in 91% yield. Finally, potassium tert-butoxide-mediated amide formation with aniline 24.5 afforded olverembatinib (24) in 88% yield.
