| Popis | C-H activation of position 3 of a substituted pyrazole ring catalyzed by palladium(II) was straightforward and convenient for arylated or heteroarylated 5,5-dimethyl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazoles. Moreover, we introduced simple protection of the nitrogen in the pyridin-2-yl directing group, which otherwise does not allow cross-coupling reaction, by transformation to the N-oxide. Selected final products were reasonably selective ALK5 kinase inhibitors. |
