In a similar manner, 4-[(3-morpholin-4-ylmethylphenyl)hydrazono]-5-pyridin-4-yl-4H-pyrazol-3-ylamine was prepared according the procedure described above in Paragraphs A and B with the following modifications: THF was used as the solvent to replace EtOH and the temperature was 55° C. for the hydrazine reaction. 3-Morpholin-4-ylmethylphenylamine (0.192 g, 1.0 mmol) and potassium salt of 3-oxo-3-pyridin-4-ylpropionitrile (0.276 g, 1.5 mmol) yielded 0.117 g of the product (32%). MS (m/z, ES+): 364.4 (M+1. 100%).
