Reaction Steps

A stirred solution of tert-butyl 4-(1-(7-(1-hydroxy-2-methylpropan-2-ylcarbamoyl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl)-1H-indazol-3-yl)piperidine-1-carboxylate (120 mg, 181 μmol) in 2,2,2-trifluoroethanol (2 mL) was heated in a microwave at 150° C. for 4 h. The mixture was concentrated in vacuo and used in the next step without purification.
