실험 절차

To a mixture of 5-{1-[4-amino-3-(difluoromethyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]ethyl}-3-azetidin-3-yl-4-methoxy-2-methylbenzonitrile dihydrochloride (25 mg, 0.051 mmol), (2S)-2-{[tert-butyl(diphenyl)silyl]oxy}propanal (18 mg, 0.057 mmol) and triethylamine (22 μL, 0.15 mmol) in methylene chloride (0.3 mL) was added sodium triacetoxyborohydride resin (45 mg, 0.10 mmol). The mixture was stirred overnight then filtered and concentrated. To the residue was added tetrahydrofuran (1.0 mL) and 1.0 M tetra-n-butylammonium fluoride in THF (0.51 mL, 0.51 mmol). The resulting mixture was stirred overnight at room temp. The solvent was evaporated and the crude material was purified using RP-HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 30 mL/min) to give 1.6 mg (6.6%) of the desired product. The product was isolated as a single diastereomer. LCMS calculated for C23H28F2N7O2 (M+H)+: m/z=472.2; Found: 472.2.
