The 6-chloro-4-(1-chloroethyl)-3-ethoxy-2-pyrrolidin-1-ylbenzonitrile (0.048 g, 0.15 mmol, racemic mixture) was combined with 3-methyl-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.034 g, 0.23 mmol) and cesium carbonate (0.10 g, 0.31 mmol) in N,N-dimethylformamide (3.0 mL) and heated in an oil bath to 85° C. After heating for 18 hrs the reaction was complete. The crude reaction was purified with out work up by prep HPLC on a C-18 column eluting water:acetonitrile gradient buffered pH 10 to give the title compound as a white amorphous solid (0.012 g, 18%). The product was isolated as a racemic mixture. LCMS calculated for C21H25ClN7O (M+H)+: m/z=426.1; found 426.1. 1H NMR (300 MHz, DMSO-d6) δ 8.11 (s, 1H), 6.91 (s, 1H), 6.25 (q, J=7.1 Hz, 1H), 3.71 (dp, J=15.7, 8.1, 7.2 Hz, 4H), 3.49-3.35 (m, 2H), 2.55 (s, 3H), 2.00-1.76 (m, 4H), 1.70 (d, J=7.1 Hz, 3H), 1.34 (t, J=7.0 Hz, 3H).
