Procedure

To a solution of 2,4-dichloropyrimidine (1 mmol) and 5-aminoindazole (1 mmol) dissolved in 5 ml EtOH was added Et3N (1 mmol). The reaction mixture was refluxed for 5 h. After removal of the solvent in vacuo and addition of H2O, the mixture was extracted with EtOAc. The organic layers were combined, washed with a saturated NaCl aqueous solution, dried over anhydrous Na2SO4, and concentrated in vacuo. The resulted oil was purified by column chromatography to give N-(2-chloropyrimidin-4-yl)-1H-indazol-5-amine in a yield of 80%.
