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-ethoxybenzonitrile (300 mg, 0.74 mmol, chiral intermediate from Example 212) in tetrahydrofuran (14 mL) was treated with triethylamine (260 μL, 1.8 mmol) followed by 2-bromoethanol (63 μL, 0.89 mmol) dropwise and stirred at 60° C. for 6 h. The reaction mixture was treated with additional 2-bromoethanol (26 μL, 0.37 mmol) and stirred at 60° C. for another 6 h. The reaction mixture was poured into saturated sodium bicarbonate solution and extracted with ethyl acetate. The organic layer was concentrated 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 (0.15 g, 44%). The product was isolated as a single enantiomer. 1H NMR (400 MHz, DMSO-d6) δ 8.19 (s, 1H), 7.56 (s, 1H), 6.36-6.25 (m, 1H), 4.48 (br s, 1H), 4.19-4.07 (m, 1H), 4.04-3.94 (m, 2H), 3.91-3.82 (m, 1H), 3.81-3.72 (m, 1H), 3.20-3.08 (m, 2H), 2.62 (s, 2H), 2.57 (s, 3H), 1.79 (d, J=6.8 Hz, 3H), 1.40 (t, J=6.6 Hz, 3H). LCMS for C22H27ClN7O2 (M+H)+: m/z=456.2; Found: 456.1.
