Tert-butyl 4-(5-(bis(tert-butoxycarbonyl)amino)-6-(5-phenyl-1,3,4-oxadiazol-2-yl)pyrazin-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (2.4 g, 3.867 mmol) was dissolved in DCM (40 mL) and treated with TFA (8 mL, 103.8 mmol). The reaction was allowed to stir overnight and then the solvent was removed in vacuo. The mixture was azeotroped with DCM (×3) and dried under vacuum to give the desired product as an orange solid (1.89 g, 100% Yield).
