Procedure

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 (20 mg, 0.04 mmol, racemic intermediate from Example 129, Step 2) and triethylamine (18 μL, 0.13 mmol) in isopropyl alcohol (0.1 mL) was added (S)-(−)-methyloxirane (9.1 μL, 0.13 mmol). The resulting mixture was stirred at 90° C. for 5 h. The crude mixture 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 2.5 mg (10%) of give the desired product. The product was isolated as a mixture of diastereomers. LCMS calculated for C23H28F2N7O2 (M+H)+: m/z=472.2; Found: 472.2.
