N2-(4-{4-amino-1-[(3R)-1-methyltetrahydro-1H-3-pyrrolyl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl}phenyl)-5,7-dimethyl-1,3-benzoxazol-2-amine was prepared from (S)-(−)-3-pyrrolidinol in a manner analogous to that used for the preparation of rac-N2-{4-[4-Amino-1-(1-methyltetrahydro-1H-3-pyrrolyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]phenyl}-5,7-dimethyl-1,3-benzoxazol-2-amine. The compound was formed as a white solid (0.195 g, 53%). 1H NMR (DMSO-d6, 400 MHz) 1H NMR (DMSO-d6, 400 MHz) 2.31-2.35 (m, 2H), 2.32 (s, 3H), 2.35 (s, 3H), 2.40 (s, 3H), 2.70-2.77 (m, 3H), 3.05 (t, 1H), 5.40 (m, 1H), 6.80 (s, 1H), 7.11 (s, 1H), 7.66 (d, 2H), 7.93 (d, 2H), 8.24 (s, 1H), 10.85 (s, 1H); RP-HPLC Rt 11.090 min, 99% purity (5% to 85% acetonitrile/0.1M aqueous ammonium acetate, buffered to pH 4.5, over 20 min at 1 mL/min; λ=254 nm; Deltapak C18, 300 Å, 5 μm, 150×3.9 mm column); m/z 455 (MH+).
