Reaction Steps

To a solution of ethyl 2,4-dichloropyrimidine-5-carboxylate (280 mg, 1.27 mmol) and 3-fluoro-4-(1H-pyrazol-1-yl)benzenamine (230 mg, 1.30 mmol) in CH3CN (8 mL) at room temperature, DIEA (0.442 mL, 2.54 mmol) was added. The mixture was stirred at room temperature for 48 h. Water (15 mL) was added to induce precipitation. The precipitate was collected, dried on vacuum to give ethyl 2-chloro-4-(3-fluoro-4-(1H-pyrazol-1-yl)phenylamino)pyrimidine-5-carboxylate as a solid (275 mg). MS 362.3 and 364.3 (M+H, Cl pattern)
