Procedure

2 mL of an 6 N aqueous solution of hydrochloride were added to the mixture of tert-butyl N-(3-{3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-azetanyl}-3-oxopropyl)-N-(2-hydroxyethyl)carbamate (0.040 g, 0.000070 mol). in acetone (5 mL). The mixture was stirred at 45° C. for 1.5 hours. The solvent was removed under removed pressure. Water (10 mL) was added to the residue, the mixture was lyophilized. 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 1-{3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-azetanyl}-3-[(2-hydroxyethyl)amino]-1-propanone (0.003 g, 0.00001 mol).
