Reaction Conditions

Reaction Steps

4-[2-(4-Fluoro-phenyl)-5-trifluoromethyl-2H-pyrazol-3-yl]-pyridin-2-ylamine (132 mg, 0.41 mmol) and benzoyl isocyanate (120 mg, 0.82 mmol) are mixed in DCM (4.0 mL) and the reaction mixture is heated at 50° C. for 16 hrs. After it is cooled down, the solvent is removed and the residue is dissolved in ethanol (2.5 mL). Potassium carbonate (70 mg, 0.49 mmol) is added and the reaction mixture is heated at 85° C. for 2 hrs before it is cooled down to room temperature. The solvent is removed and the residue is partitioned between water (30 mL) and EtOAc (50 mL). The organic layer is separated and concentrated to give the crude product. Purification by flash column chromatography using MeOH in DCM (gradient from 0% to 10%) affords 21 mg of the titled product.
