To 2,4-Dichloro-5-phenyl-pyrimidine (187 mg, 0.83 mmol) and triethylamine (255 μL, 1.83 mmol) in ethanol (25 mL) was added 5-Cyclopropyl-2H-pyrazol-3-ylamine (142 mg, 1.16 mmol) and the solution was heated to 80 C for 14 h. The solvent was removed in vacuum, and the title compound was obtained by flash chromatography (0-2% methanol in dichloromethane) to give: 150 mg (60% yield). HPLC tr=6.68 min (87%), LCMS m/e 312.1 (M+H), 310.0 (M-H).
