実験手順

3-Bromo-5,6-di-p-tolylpyrazin-2-amine (Example 1, step 3) (200 mg, 0.565 mmol) in anhydrous dioxane (10 ml), degassed with N2 was treated with triethylamine (0.708 ml, 5.08 mmol), hept-6-ynoic acid (0.179 ml, 1.129 mmol), copper(I) iodide (32.3 mg, 0.169 mmol) and PdCl2(dppf)-CH2Cl2-adduct (46.1 mg, 0.056 mmol). The reaction mixture was stirred at room temperature for 16 hours. The resulting mixture was diluted with DCM (10 ml) and dry loaded onto silica. Purification by chromatography on silica eluting with 0-100% EtOAc in iso-hexane followed by 20% MeOH in EtOAc afforded the titled compound;
