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 (Intermediate 2) (0.075 g, 0.14 mmol), 1-(2-methoxyethyl)-piperazine (0.039 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 1-(2-methoxyethyl)-piperazine (0.10 mL) and sodium triacetoxyborohydride (0.089 g, 0.41 mmol) were added and the reaction mixture was shaken for 16 h. 1N NaOH (1 mL) was added and the resulting solution was extracted with two portions of dichloromethane (2 mL each). The combined organic portions were concentrated to afford a brown solid which was 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 16.9-20.2 min was collected, concentrated, and lyopholized to afford N1-{4-[4-amino-1-(4-{[4-(2-methoxyethyl)piperazino]methyl}phenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-(trifluoromethyl)benzamide as a white solid (0.021 g, 0.031 mmol): 1H NMR (d6-DMSO, 400 MHz): δH 9.94 (1H, s), 8.34-8.37 (2H, m), 8.14-8.17 (1H, m), 7.98-8.02 (1H, m), 7.89 (1H, d, J=10.4 Hz), 7.74-7.76 (1H, m), 7.34-7.64 (6H, m), 3.96 (3H, s), 3.51 (2H, s), 3.31-3.43 (2H, m), 3.22 (3H, s), and 2.41-2.45 (10H, 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 11.24 min.
