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 dichloromethane (1 mL) was treated with triethylamine (20 μL, 0.14 mmol) followed by methyl chloroformate (4.7 μL, 0.06 mmol) and stirred at room temperature for 1 h. 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 (12 mg, 52%). The product was isolated as a single enantiomer. 1H NMR (300 MHz, DMSO-d6) δ 8.11 (s, 1H), 7.51 (s, 1H), 7.34 (br s, 2H), 6.25 (q, J=7.0 Hz, 1H), 4.53-4.38 (m, 1H), 4.36-4.17 (m, 4H), 3.71 (s, 3H), 3.55 (s, 3H), 2.55 (s, 3H), 1.73 (d, J=7.1 Hz, 3H). LCMS for C21H23ClN7O3 (M+H)+: m/z=456.2; Found: 456.1.
