Copper(II)-catalyzed boronic acid promoted C-Nbondcross-coupling reactions have been successfully developed for sequential N-arylation of C-amino-NH-azoles. These general protocols are compatible with a variety of aryl/hetero-aryl boronic acids and provided rapid access to a diverse array of diarylaminoazole derivatives in a two-step sequence or in one-pot.
The invention relates to new derivatives of formula (I),
wherein the substituents are as defined in the specification; to processes for the preparation of such derivatives; pharmaceutical compositions comprising such derivatives; such derivatives as a medicament; such derivatives for the treatment of one or more IGF-1R mediated disorders or diseases.
