Versuchsvorschrift

The title compound was prepared according to a procedure similar to that described in Procedure G. Into a 8-mL sealed tube purged and maintained with an inert atmosphere of nitrogen, was placed a suspension 9-Bromo-8-fluoro-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-2-carboxylic acid amide (200 mg, 0.58 mmol, 1.00 equiv), 2-(pyridin-2-yl)but-3-yn-2-ol (300 mg, 2.04 mmol, 3.50 equiv) and Pd(PPh3)2Cl2 (200 mg, 0.28 mmol, 0.50 equiv) in DMSO (0.5 mL) and triethylamine (0.5 mL). The final reaction mixture was irradiated with microwave radiation for 3 h at 70° C. The resulting solution was diluted with 50 mL of ethyl acetate. The resulting mixture was washed with 3×25 mL of water. The mixture was dried over sodium sulfate and concentrated under vacuum. The residue was purified by Prep-HPLC with the following conditions (1#-Pre-HPLC-016(Waters)): Column, XSelect Prep C18; mobile phase, water with 0.05% NH3H2O and CH3CN (23% CH3CN up to 63% in 10 min, hold 3 min); Detector, uv 254/220 nm. This resulted in 18 mg (7%) of 8-Fluoro-9-(3-hydroxy-3-pyridin-2-yl-but-1-ynyl)-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulene-2-carboxylic acid amide as a light yellow solid. LC-MS (ES, m/z): 410[M+H]+; 1H-NMR (400 MHz, DMSO-d6, ppm) δ 8.657 (d, 1H), 8.574 (d, 1H), 8.482 (s, 1H), 7.884 (m, 2H), 7.792 (d, 1H), 7.352 (m, 1H), 7.020 (d, 1H), 6.383 (s, 1H), 4.386 (t, 2H), 3.408 (t, 2H), 1.841 (s, 3H).
