Procedure

To a mixture of 1-[1-(3-azetidin-3-yl-5-chloro-2-methoxy-4-methyl phenyl)ethyl]-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine dihydrochloride (15 mg, 0.033 mmol, chiral intermediate from Example 1, Step 7, peak 1), mixture of (2S)-2-hydroxypropanoic acid (4.3 μL, 0.049 mmol) (L-lactic acid, 85% aq.) and triethylamine (14 μL, 0.098 mmol) in N,N-dimethylformamide (0.2 mL) was added N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (19 mg, 0.049 mmol). The resulting mixture was stirred overnight at room temperature. The mixture was diluted with 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 3.0 mg (20%) of the desired product. The product was isolated as a single enantiomer. LCMS calculated for C22H28ClN6O3 (M+H)+: m/z=459.2; Found: 459.2.
