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 (20 mg, 0.044 mmol, chiral intermediate from peak 1 of Example 1, Step 7), (2R)-2-(trifluoromethyl)oxirane (9.4 μL, 0.11 mmol), and triethylamine (18 μL, 0.13 mmol) in ethanol (0.3 mL) was heated in a microwave at 120° C. for 25 min. The mixture was diluted with MeOH and 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 6.2 mg (28%) of the desired product. The product was isolated as a single enantiomer. LCMS calculated for C22H27ClF3N6O2(M+H)+: m/z=499.2; Found: 499.1.
