Reaction Steps

A solution of the bromopyridine compound prepared in step 3 of Example A-219 (250 mg, 0.75 mmol) in phenethylamine (5 ml) was heated at 175° C. for six hours under a nitrogen atmosphere. The excess amine was distilled off under high vacuum and the residue was dissolved in ethyl acetate and washed with water. After drying over magnesium sulfate and removal of solvent, the residue was chromatographed on silica gel with mixtures of ethyl acetate and toluene to give 4-[3-(3-chlorophenyl)-1H-pyrazol-4-yl]-N-(phenylethyl)-2-pyridinamine (230 mg, 81%) as a solid, m.p. 185-186° C.
