Reaction Steps

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 (21 mg, 0.043 mmol, racemic intermediate from Example 129, Step 2), 2-bromo-1,1-difluoroethane (3.8 μL, 0.048 mmol), and triethylamine (18 μL, 0.13 mmol) in N,N-dimethylformamide (0.3 mL) was stirred overnight at 70° C. The mixture was diluted with methanol (MeOH) and 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 3.3 mg (16%) of the desired product. The product was isolated as a racemic mixture. LCMS calculated for C22H24F4N7O (M+H)+: m/z=478.2; Found: 478.1.
