Procedure

To a solution of 4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]-2-pyridinecarbonitrile from step 2 (0.45 g, 0.0017 mol) in 10 mL of DMSO was added hydrogen peroxide (0.24 mL of 30% aqueous solution, 1.7 mmol) and potassium carbonate (0.04 g, 0.4 mmol) at 0° C. The mixture was stirred for 1 hour while allowing it to warm to room temperature. Water was added and the precipitate was collected by filtration and air-dried to give 0.32 g of 4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]-2-pyridinecarboxamide as a white solid (67% yield), mp: 230-231° C. Anal. Calc'd for C15H11FN4O: C, 63.83; H, 3.93; N, 19.85. Found C, 63.42; H, 3.66; N. 19.58.
