Procedure

To a mixture of 2-(1-isopropyl-1H-1,2,4-triazol-5-yl)-9-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (600 mg, 1.42 mmol) and 1-(4-bromo-1-(tetrahydro-pyran-2-yl)-1H-imidazol-2-yl)-2-methyl-propan-2-ol (648 mg, 2.1 mmol) in dry DMF (6 mL) under nitrogen was added CsF (534 mg, 3.53 mmol), CuI (27 mg, 0.14 mmol) and Pd(PPh3)4 (81 mg, 0.07 mmol). The reaction mixture was heated at 120° C. for 20 min in a microwave reactor. It was filtered, concentrated and purified by column chromatography (DCM/MeOH=20:1) to give 1-[4-[2-(2-isopropyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-8-yl]-1-(tetrahydro-pyran-2-yl)-1H-imidazol-2-yl]-2-methyl-propan-2-ol as brown oil (1.1 g). LCMS: (ESI, m/z)=518 [M+H]+.
