Reaction Steps

To a solution of tert-butyl N-tert-butoxycarbonyl-N-[3-(5-phenyl-1,3,4-oxadiazol-2-yl)-5-vinyl-pyrazin-2-yl]carbamate (138 mg, 0.3 mmol) in DCM (0.7 mL) at room temperature under an atmosphere of N2 was added TFA (338 mg, 228 μL, 3 mmol) and reaction mixture was stirred for 20 minutes. The reaction mixture was diluted with DCM and slowly quenched with satd. NaHCO3. The layers were separated and the organic layer was dried over Na2SO4, filtered and concentrated to yield 3-(5-phenyl-1,3,4-oxadiazol-2-yl)-5-vinyl-pyrazin-2-amine (67 mg, 85%) as a yellow solid. LC/MS m/z 266.4 [M+H]+.
