Procedure

A mixture of 5-cyclopropyl-1H-pyrazol-3-amine (246 mg, 2.00 mmol), 2,4,5-trichloropyrimidine (367 mg, 2.00 mmol, 1 equiv.) and Na2CO3 (233 mg, 2.20 mmol, 1.1 equiv.) in EtOH (10 mL) was heated at 40° C. for 16 h. The crude reaction mixture was diluted with EtOAc and sequentially washed with: water (3×) and saturated aqueous NaCl (1×). The resulting EtOAc layer was dried over Na2SO4 and then concentrated in vacuo, providing 2,5-dichloro-N-(5-cyclopropyl-1H-pyrazol-3-yl)pyrimidin-4-amine; ESMS m/z 270.0 (M+H+).
