Procedure

A solution of 4-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-2-azetidin-3-yl-6-chloro-3-methoxybenzonitrile (chiral intermediate from Example 261) (20 mg, 0.05 mmol) in N,N-dimethylformamide (1 mL) was treated with triethylamine (20 μL, 0.14 mmol) followed by 2-isocyanato-2-methyl-propane (7.2 μL, 0.063 mmol) and stirred at room temperature overnight. The reaction mixture was diluted with methanol and purified by preparative LCMS (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.1% ammonium hydroxide, at flow rate of 60 mL/min) to give the desired product (16 mg, 64%). The product was isolated as a single enantiomer. LCMS for C24H30ClN8O2 (M+H)+: m/z=497.2; Found: 497.2.
