実験手順
3-(Cyclopropylethynyl)-5,6-di-p-tolylpyrazin-2-amine (step 4)(279 mg, 0.822 mmol) in tert-BuOH (10 ml) was treated with potassium tert-butoxide (184 mg, 1.644 mmol) and heated at reflux for 6 hours. The mixture was diluted with water and extracted with DCM (×3). The combined organic extracts were concentrated under reduced pressure and purification of the crude product by chromatography on silica eluting with 0-20% EtOAc in iso-hexane afforded the titled compound as a beige coloured solid;
