Procedure

4-Bromo-2-methyl-2H-pyrazol-3-ylamine (0.2 g, 1.14 mmol) and 2-chloro-6-phenyl-pyridine (0.32 g, 1.7 mmol) were dissolved in DMF (5 mL) then sodium hydride (60% dispersion in oil, 0.09 g, 2.3 mmol) was added. The reaction was heated to 100° C. for 30 minutes then cooled and submitted to standard aqueous workup. The residue was purified on silica gel (0-40% EtOAc in hexanes) to provide the title compound.
