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) (40 mg, 0.10 mmol) in dichloromethane (1 mL) was treated with triethylamine (35 μL, 0.25 mmol), cooled to 0° C., treated with methanesulfonyl chloride (9.3 μL, 0.12 mmol) and stirred at 0° C. 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 (20 mg, 42%). The product was isolated as a single enantiomer. 1H NMR (300 MHz, DMSO-d6) δ 8.12 (s, 1H), 7.55 (s, 1H), 7.35 (br s, 2H), 6.25 (q, J=7.0 Hz, 1H), 4.54-4.40 (m, 1H), 4.27-4.12 (m, 4H), 3.68 (s, 3H), 3.01 (s, 3H), 2.55 (s, 3H), 1.74 (d, J=7.1 Hz, 3H). LCMS for C20H23ClN7O3S (M+H)+: m/z=476.1; Found: 476.1.
