Versuchsvorschrift

A solution of 2-[[1-(2-aminopyrimidin-4-yl)-6-bromo-1H-1,3-benzodiazol-2-yl]oxy]ethan-1-ol (200 mg, 0.57 mmol), 2-(5-chloropyridin-2-yl)but-3-yn-2-ol (518 mg, 2.85 mmol), bis(triphenylphosphine)palladium(II) dichloride (400 mg, 0.57 mmol) and triethylamine (0.5 mL) in DMSO (0.5 mL) was irradiated under nitrogen in a 10-mL sealed tube with microwave radiation for 2 h at 100° C. The reaction mixture was cooled to room temperature and the solid material was removed by filtration. The filtrate was concentrated under vacuum and the crude product (50 mg) was purified by preparative HPLC to give 2 mg (1%) of 4-[1-(2-aminopyrimidin-4-yl)-2-(2-hydroxyethoxy)-1H-1,3-benzodiazol-6-yl]-2-(5-chloropyridin-2-yl)but-3-yn-2-ol as a light yellow solid: 1H NMR (400 MHz, DMSO) delta 8.61 (s, 1H), 8.38 (d, J=5.6 Hz, 1H), 8.16 (s, 1H), 7.98-7.82 (m, 1H), 7.81 (d, J=8.4 Hz, 1H), 7.43 (d, J=8.4 Hz, 1H), 7.26-7.24 (m, 1H), 7.06 (d, J=5.2 Hz, 3H), 6.44 (s, 1H), 5.06 (t, J=5.6 Hz, 1H), 4.61 (t, J=4.8 Hz, 2H), 3.83-3.80 (m, 2H), 1.82 (s, 3H); LC-MS: m/z=+451 (M+H)+.
