Procedure

A mixture of 8-bromo-2-(2-isopropyl-5-methoxymethyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene (100 mg, 0.24 mmol), 2-methyl-1-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyrazol-1-yl]-propan-2-ol (127 mg, 0.48 mmol), PdC12(dppf).DCM (9.8 mg, 0.012 mmol), cesium carbonate (234 mg, 0.72 mmol), DME (1.6 mL), water (0.27 mL) and IMS (0.5 mL) was degassed and then heated at 140° C. for 20 min using microwave irradiation. The reaction mixture was partitioned between DCM and water, the aqueous extracted twice with DCM and the combined organic extracts washed with brine then dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was subjected to RPHPLC (C18 column, gradient 5 to 95% methanol in water+0.1% HCO2H) to give 302 as a white solid (40 mg, 35%). LCMS: RT=3.77 min, [M+H]+ 478. 1H NMR 400 MHz (DMSO-d) δ: 8.37 (1H, d, J=8.38 Hz), 8.17 (1H, s), 7.94 (2H, d, J=7.28 Hz), 7.40 (1H, dd, J=8.37, 1.80 Hz), 7.28 (1H, d, J=1.77 Hz), 5.89-5.88 (1H, m), 4.74 (1H, s), 4.53 (4H, m), 4.38 (2H, s), 4.04 (2H, s), 3.32 (3H, s), 1.49 (6H, d, J=6.60 Hz), 1.10 (6H, s).
