Procedure

A mixture of N1-{4-[4-amino-1-(4-formylphenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-(trifluoromethyl)benzamide (0.075 g, 0.14 mmol), (S)-3-hydroxypyrrolidine (0.024 g, 0.27 mmol), and sodium triacetoxyborohydride (0.087 g, 0.41 mmol) in dichloroethane (1.4 mL) was shaken at room temperature for 3 days. Additional portions of (S)-3-hydroxypyrrolidine (0.1 mL) and sodium triacetoxyborohydride (0.084 g, 0.40 mmol) were added and the reaction mixture was shaken for 3 days. Acetic acid (0.1 mL) was added and the reaction mixture was shaken for 4 days. 1N NaOH (1 mL) was added and the reaction mixture was concentrated in vacuo. The residue was dissolved in DMF (2 mL), filtered through a syringe-tip Acrodisc filter, and purified by preparative RP-HPLC (Rainin C18, 8 μm, 300 Å, 25 cm; 20-80% acetonitrile-0.05 M ammonium acetate over 25 min, 21 mL/min); the fraction eluting from 16.5-18.4 min was collected, concentrated, and lyopholized to afford N1-{4-[4-amino-1-(4-{[(3R)-3-hydroxytetrahydro-1H-1-pyrrolyl]methyl}phenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-(trifluoromethyl)benzamide as a white solid (0.027 g, 0.043 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 9.89 (1H, s), 8.30-8.33 (2H, m), 8.13-8.14 (2H, m), 7.90-7.80 (1H, m), 7.84 (1H, d, J=10.8 Hz), 7.70 (1H, d, J=7.6 Hz), 7.35-7.59 (4H, m), 4.64 (1H, bs), 4.14-4.23 (1H, m), 3.91 (3H, s), 3.62 (2H, s), 2.61-2.62 (2H, m), 2.27-2.28 (2H, m), 2.27-2.28 (2H, m), 2.02 (1H, m), and 1.60 (1H, m); RP-HPLC (Hypersil C18, 5 μm, 100 Å, 15 cm; 5%-100% acetonitrile-0.1 M ammonium acetate over 15 min, 1 mL/min). Rt 10.41 min. MS: MH+ 622.2.
