실험 절차

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 2-(5-methylisoxazol-3-yl)but-3-yn-2-ol (515 mg, 3.41 mmol, 3.50 equiv), 13-bromo-9-oxa-3,6-diazatricyclo[8.4.0.02,6]tetradeca-1(14),2,4,10,12-pentaene-4-carboxamide (300 mg, 0.97 mmol, 1 equiv) and Pd(PPh3)2Cl2 (205 mg, 0.29 mmol, 0.3 equiv) in DMSO (2 mL) and triethylamine (2 mL). The final reaction mixture was irradiated with microwave radiation for 2 h at 70° C. The resulting mixture was washed with 1×100 mL of water and 2×100 mL of CH3CN. The solids were collected by filtration. The residue was further purified by Chiral-Prep-HPLC with the following conditions (2#-Gilson Gx 281(HPLC-09): Column, Chiralpak IA2*25 cm, 5 um Chiral-P(IA)004IA00CJ-MB003; Phase A:MTBE Phase B:EtOH (0.2% DEA)-HPLC (10.0% EtOH for 60 min, then down to 0%); Detector, uv 254/220 nm. This resulted in 34.2 mg (9%) of 9-[(S)-3-Hydroxy-3-(5-methyl-isoxazol-3-yl)-but-1-ynyl]-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene-2-carboxylic acid amide as a off-white solid LC-MS (ES, m/z): 379[M+H]+; 1H-NMR (400 MHz, DMSO-d6, ppm): δ 8.536 (s, 1H), 7.802 (s, 1H), 7.558 (br s, 1H), 7.340-7.300 (m, 1H), 7.143 (br s, 1H), 7.040 (d, 1H), 6.504 (s, 1H), 6.360 (s, 1H), 4.492 (s, 4H), 2.365 (s, 3H), 1.920 (s, 3H).
