실험 절차

7-(3-Amino-5,6-di-p-tolylpyrazin-2-yl)hept-6-ynoic acid (step 1) (137 mg, 0.343 mmol) in tert-BuOH (3 ml) was treated with potassium tert-butoxide (154 mg, 1.372 mmol) and stirred at reflux for 3 hours. The mixture was added to water (50 ml) and extracted with DCM (×3). The organic solvent was removed under reduced pressure and the crude material was dissolved in EtOH (minimal) and excess of water was added. The resulting suspension was sonicated and filtered, rinsing the filter cake with water (×3). Purification of crude product by chromatograpy on silica eluting with 0-1% MeOH in DCM afforded the titled compound;
