실험 절차

To a nitrogen purged flask charged with 10% Pd/C (0.033 g, 0.310 mmol) was added enough methanol to cover the catalyst. To this mixture was added a solution of (R,E)-ethyl 4-((5-fluoro-2-(5-fluoro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidin-4-yl)amino)-5,5-dimethylhex-2-enoate, 38a, (0.330 g, 0.579 mmol) in MeOH. Note, a small amount of EtOAc was added to fully solubilize the starting material. The reaction mixture was then stirred under 1 atmosphere of hydrogen for 3 hours. LCMS shows presence of significant amounts of starting material. The contents of the reaction mixture were transferred to a pressure vessel containing a fresh source of palladium (0.033 g, 0.310 mmol). The reaction mixture was stirred in a Parr hydrogenation flask under 46 psi of hydrogen overnight. The mixture was diluted with methanol and filtered through celite. The filtrate was concentrated in vacuo to afford 331 mg of the desired product that was used without further purification: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, RT=3.75 minutes (M+H) 572.35.
