Reaction Steps

A solution of the bromopyridine compound prepared in step 3 of Example A-219 (150 mg, 0.5 mmol) in benzylamine (5 ml) was heated at 175° C. for six hours. After cooling, excess benzylamine was removed by high vacuum distillation and ethyl acetate added to the residue. After washing the organic phase with water and drying over magnesium sulfate, the solvent was removed in vacuo and the residue chromatographed on silica gel using mixtures of ethyl acetate and toluene to give 4-[3-(3-chlorophenyl)-1H-pyrazol-4-yl]-N-(phenylmethyl)-2-pyridinamine (110 mg, 61%) as a solid, m.p. 179-180 ° C.
