C4-Alkylamination of C4-Halo-1H-1-tritylpyrazoles Using Pd(dba)(2) or CuI

Alkylamino coupling reactions at the C4 positions of 4-halo-1H-1-tritylpyrazoles were investigated using palladium or copper catalysts. The Pd(dba)(2) catalyzed C-N coupling reaction of aryl- or alkylamines, lacking a β-hydrogen atom, proceeded smoothly using (t)BuDavePhos as a ligand. As a substrat...
