A 1 M solution of hydrazine in THF (0.090 ml, 88.5 mmol) was added to 3-((E)-3-dimethylamino-2-pyridin-4-yl-acryloyl)benzonitrile (6.13 g, 22.1 mmol) and the mixture was stirred at 60° C. for 1 h. The product 3-(4-pyridin-4-yl-1H-pyrazol-3-yl)-benzonitrile (4.89 g, 19.8 mmol, 90%) was isolated as a white solid by filtration from the reaction mixture.
