実験手順

9-bromo-2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine 411 (0.5 g, 0.001 mol) and vinyltrifluoroborane/potassium hydride (0.34 g, 0.0026 mol) was dissolved in THF (5 mL) and 1 mL H2O (Tremblay-Morin et al (2006) Tetrahedron Letters 47(18):3043-3046). Cesium Carbonate (1.2 g, 0.0039 mol) was added and mixture was degassed with N2 for 10 minutes. Tetrakis(triphenylphosphine)palladium(0) (0.074 g, 0.064 mmol) was added. The reaction vessel was sealed and was heated at 110 C in an oil bath overnight. The reaction mixture was cooled to room temperature and the seal was removed. The crude product was isolated from an aqueous workup using H2O and brine. The crude product was purified using flash column chromatography (0-10% MeOH in DCM) to give 2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-9-vinyl-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (0.300 g, 89% yield
