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 (200 mg, 0.48 mmol) and 1-(4-bromo-1-methyl-1H-imidazol-2-yl)-2-methyl-propan-2-ol (166 mg, 0.71 mmol) in dry DMF (2 mL) under nitrogen was added CsF (180 mg, 1.19 mmol), CuI (9 mg, 0.048 mmol) and Pd(PPh3)4 (27 mg, 0.024 mmol). The reaction mixture was heated at 130° C. for 40 min under microwave. Cooled to room temperature, the resulting mixture was poured into water and extracted with EtOAc. Dried organics over sodium sulfate and purified by pre-HPLC to give 272 as a white solid (34.9 mg, yield: 16%). 1H NMR (DMSO-d6, 400 MHz): δ8.51 (s, 1H), 7.90 (s, 1H), 7.86 (s, 1H), 7.23-7.11 (m, 3H), 5.93-5.89 (m, 1H), 4.54-4.52 (m, 4H), 3.74-3.66 (m, 5H), 1.46 (dd, J=6.4 Hz, 6H), 1.24 (brs, 6H). MS: (ESI, m/z)=448 [M+H]+
