Procedure

To a mixture of 3-(4-phenoxyphenyl)-1-(4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.05 g, 0.00013 mol) and potassium carbonate (0.036 g, 0.00026 mol) in anhydrous N,N-dimethylformamide (3 mL) was added chloroacetylchloride (0.028 g, 0.00026 mol) at room temperature. The mixture was stirred for 10 min. before 2-aminoimidazole sulfate (0.18 g, 0.0014 mol) and potassium carbonate (0.19 g, 0.0014 mol) were added. The mixture was stirred at room temperature for 18 hours then warmed to 60° C. for 6 hours. The solvent was removed under reduced pressure. The residue was dissolved in dichloromethane (3 mL) and washed with water (2 mL). The solvent was removed under reduced pressure. The residue was purified by RP-HPLC (Hypersilprep HS C18, 8 μm, 250×21.1 mm; 5%-100% over 35 min with 0.1 M ammonium acetate, 21 mL/min) to yield 2-(2-amino-1H-1-imidazolyl)-1-{4-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidino}-1-ethanone acetate (0.015 g, 0.00003 mol).
