Procedure

A mixture of 3-(4-phenoxyphenyl)-1-(4-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (0.05 g, 0.00013 mol), 3-[(tert-butoxycarbonyl)(2-hydroxyethyl)amino]propanoic acid (0.038 g, 0.000163 mol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.031 g, 0.000163 mol), N,N-diisopropylethylamine (0.031 g, 0.00024 mol) and 1-hydroxy-7-azabenzotriazole (0.018 g, 0.00013 mol) in anhydrous dichloromethane (5 mL) was stirred for 18 hours at room temperature. 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 tert-butyl N-(3-{4-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidino}-3-oxopropyl)-N-(2-hydroxyethyl)carbamate (0.050 g, 0.000083 mol).
