Versuchsvorschrift

To a solution of {3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-3-yl}acetonitrile dihydrochloride (2.6 g, 6.3 mmol) in THF (30 mL) were added tert-butyl 3-oxo-8-azabicyclo[3.2.1]octane-8-carboxylate (1.3 g, 6.3 mmol), N,N-diisopropylethylamine (4.4 mL, 25 mmol) and sodium triacetoxyborohydride (2.2 g, 10 mmol). The mixture was stirred at room temperature overnight and quenched by addition of 20 mL of brine. The solution was extracted with EtOAc. The extract was dried over anhydrous Na2SO4. After removing solvent, the residue was purified by combiflash column eluting with 30-80% EtOAc in hexanes to give the desired product tert-butyl 3-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}-8-azabicyclo[3.2.1]octane-8-carboxylate. LC-MS: 619.3 (M+H)+.
