Procedure

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 (15 mg, 0.033 mmol) (chiral material, from Example 1, step 7, peak 1) and triethylamine (14 μL, 0.098 mmol) in methylene chloride (0.2 mL) was added 1-methyl-1H-pyrazole-4-carbonyl chloride (from Maybridge, 6.1 mg, 0.042 mmol). The resulting mixture 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 7.1 mg (44%) of the product. The product was isolated as a single enantiomer. LCMS calculated for C24H28ClN8O2 (M+H)+: m/z=495.2; Found: 495.2.
