(S)-tert-butyl 2-(2-cyclopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propanoate → (S)-2-(2-cyclopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propanoic acid

Participants

Reaction Steps

A solution of (S)-tert-butyl 2-(2-cyclopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propanoate (265 mg, 0.58 mmol) in 2,2,2-trifluoroethanol (4 mL) was heated at 150° C. for 3 h under microwave assisted conditions. The solvent was removed under vacuum to give 230 mg (98%) of (S)-2-(2-cyclopropyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propanoic acid as an oil.
