実験手順

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) and tert-butyl 2-methyl-4-oxopiperidine-1-carboxylate (1.3 g, 6.3 mmol) in THF (30 mL) were added N,N-diisopropylethylamine (4.4 mL, 25 mmol) and sodium triacetoxyborohydride (2.2 g, 10 mmol). The mixture was stirred at room temperature overnight. After addition of 20 mL of brine, the solution was extracted with EtOAc. The extract was dried over anhydrous Na2SO4 and filtered. After removing the solvent, the residue was purified by combiflash chromatography eluting with 30-80% EtOAc in hexanes to give 2.6 g (81%) of the desired product tert-butyl 4-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}-2-methylpiperidine-1-carboxylate. LC-MS: 607.3 (M+H)+.
