Participants

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), acetyl chloride (3.4 μL, 0.048 mmol), and triethylamine (18 μL, 0.13 mmol) in methylene chloride (0.3 mL) was stirred overnight at room temperature. The solvents were 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 the desired product. The product was isolated as a racemic mixture. LCMS calculated for C22H24F2N7O2 (M+H)+: m/z=456.2; Found: 456.2.
