Reaction Steps
To a mixture of 1-[1-(3-azetidin-3-yl-5-chloro-2-methoxy-4-methylphenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine dihydrochloride (21 mg, 0.046 mmol, racemic intermediate from Example 2, Step 1)), tetrahydro-4H-pyran-4-one (from Aldrich, 4.6 μL, 0.050 mmol), and triethylamine (20 μL, 0.14 mmol) in methylene chloride (0.32 mL) was added resin of sodium triacetoxyborohydride (40 mg, 0.091 mmol). The resulting mixture was stirred overnight at rt. The mixture was filtered and concentrated and then purified by 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 C24H32ClN6O2 (M+H)+: m/z=471.2; Found: 471.2.
