Versuchsvorschrift

To a stirred solution of 5-bromo-6-methyl-7-(1,4-oxazepan-4-ylmethyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (100 mg, 0.29 mmol) and tetrakis(triphenylphosphine)-palladium(0) (101 mg, 0.088 mmol), in degassed 1,4 dioxane (4.0 mL), was added Intermediate AAN (1-[2-fluoro-5-(trifluoromethyl)phenyl]-3-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]urea) (248 mg, 0.59 mmol), K2CO3 (162 mg, 1.18 mmol), and H2O (0.4 mL). The mixture was degassed and heated (90° C.) for 17 h and then cooled to rt. The mixture was partitioned between ethyl acetate (25 mL) and saturated aqueous Na2CO3 solution (25 mL). The layers were separated and the organic phase was washed, dried (Na2SO4), and concentrated to dryness. The residue was purified by preparative HPLC using a gradient elution from 10% to 70% acetonitrile to obtain 24 mg (15%) of the desired product. 1H-NMR (DMSO-d6) δ 9.36 (s, 1H), 8.98-8.97 (m, 1H), 8.63 (dd, J=2.4, 7.2 Hz, 1H), 7.85 (s, 1H), 7.60-7.47 (m, 3H), 7.41-7.33 (m, 1H), 7.33 (d, J=8.7 Hz, 2H), 3.95 (s, 2H), 3.66 (t, J=6.0 Hz, 2H), 3.59-3.56 (m, 2H), 3.31 (m, 2H), 2.68-2.62 (m, 4H), 2.10 (s, 3H), 1.83-1.75 (m, 2H); MS [M+H]+=558.1; LCMS RT=2.94.
