Reaction Steps

A mixture of 2-chloro-4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]pyrimidine (0.37 g; 0.0013 mol; prepared as set forth in Example A-299), 7 mL of 2-fluoroaniline and 2 drops of methanol was heated at 180° C. in a sealed tube for 16 hours. Excess amine was removed by vacuum distillation and the residue was treated with ethyl acetate to give 0.35 g of N-(2-fluorophenyl)-4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]-2-pyrimidinamine as a yellow solid (77%), mp: 239-240° C. Anal. Calc'd. for C19H13F2N5: C, 65.33; H, 3.75; N, 20.05. Found: C, 64.95; H, 3.80; N, 19.77.
