Versuchsvorschrift

A mixture of N2-{4-[4-amino-1-(3-piperidyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]phenyl}-5,7-dimethyl-1,3-benzoxazol-2-amine acetate (0.04 g, 0.000078 mol), dimethylglycine (0.01 g, 0.000097 mol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.019 g, 0.000097 mol), N,N-diisopropylethylamine (0.033 g, 0.00026 mol) and 1-hydroxy-7-azabenzotriazole (0.011 g, 0.000078 mol) in anhydrous dichloromethane (5 mL) was stirred for 18 hours at room temperature. The solvent was removed under reduced pressure. The residue was partitioned between water and dichloromethane. The aqueous layer was extracted with dichloromethane, and the combined organic solvent was washed with brine. The solvent was removed under reduced pressure, and 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-[(5,7-dimethyl-1,3-benzoxazol-2-yl)amino]phenyl}-1H-pyrazolo[3,4-d]pyrimidin-1-yl)piperidino]-2-(dimethylamino)-1-ethanone acetate (0.015 g, 0.00003 mol). 1H NMR (DMSO-d6, 400 MHz) δ 10.85 (s, 1H), 8.27 (d, 1H), 7.94 (d, 2H), 7.67 (d, 2H), 7.11 (s, 1H), 6.51 (s, 1H), 4.81-1.91 (br, 11H), 2.40 (s, 3H), 2.34 (s, 3H), 2.26 (s, 3H), 2.22 (s, 3H), 1.91 (s, 3H). RP-HPLC (Delta Pak C18, 5 μm, 300A, 15 cm; 5%-85% acetonitrile—0.1M ammonium acetate over 10 min, 1 mL/min) Rt 9.7 min.
