Versuchsvorschrift

A mixture of 3-iodo-1H-pyrazolo[3,4-d]pyrimidin-4-ylamine (11.0 g, 41.1 mmol), 2-(chloromethyl)-1-phenyl-1H-benzo[d]imidazole (10.0 g, 41.4 mmol) and K2CO3 (6.0 g, 43.4 mmol) in DMSO (60 mL) was stirred at room temperature overnight. Then the mixture was added H2O (100 mL) and extracted with EtOAc (100 mL×3). The combined organic layers were concentrated in vacuo, and the residue was purified by column chromatography on silica gel (PE:EtOAc=2:1) to give 141 (10.0 g, yield 52%) as a yellow solid. LCMS (ESI), M+H+=466.04. 1HNMR (400 MHz, CDCl3) δ 5.783 (s, 2H), 5.785 (s, 2H), 7.068-7.090 (q, J=0.8 Hz, 1H), 7.088-7.307 (m, 3H), 7.362-7.422 (m, 4H), 7.800-7.822 (d, J=0.8 Hz, 1H), 8.219-8.221 (d, J=1.2 Hz, 2H)
