Reaction Steps

A solution of the bromopyridine compound prepared in step 3 of Example A-219 (300 mg, 0.9 mmol) in ethylamine (3.5 ml) and ethanol (5 ml) as heated at 150° C. in a sealed tube for 9 hours. The solvent was removed in vacuo and the residue chromatographed on silica gel with 70 ethyl acetate/30 toluene to give 4-[3-(3-chlorophenyl)-1H-pyrazol-4-yl]-N-ethyl-2-pyridinamine (125 mg, 46%) as a solid, m.p. 186-187° C.
