실험 절차

A mixture of tert-butyl {1-[4-(2-bromo-9H-imidazo[1,2-d]pyrido[2,3-b][1,4]benzodiazepin-3-yl)phenyl]cyclobutyl}carbamate (50 mg, 0.09 mmol), di-tert-butyl[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyrimidin-2-yl]imidodicarbonate (75 mg, 0.18 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (6.3 mg, 0.01 mmol) and K3PO4 (72 mg, 0.27 mmol) in DMF/water (0.9 mL, 6:1, v/v) was heated at 160° C. under microwave irradiation for 1 hour. After cooling to room temperature, the mixture was diluted with EtOAc and washed with water (×3). The organic layer was dried over anhydrous Na2SO4 and concentrated. The residue was purified by HPLC. The fraction was evaporated and the residue was dissolved in methanol (10 mL) and 4M HCl in dioxane (10 mL). After overnight reaction, the mixture was evaporated and the residue was purified by HPLC to give the titled compound as a white solid (24 mg, 43%). 1HNMR (DMSO-d6) 400 MHz δ: 8.56 (s, 1H), 8.26 (d, J=15.5 Hz, 2H), 8.08 (dd, J=4.6, 1.7 Hz, 1H), 7.93 (dd, J=8.0, 1.7 Hz, 1H), 7.50 (d, J=8.6 Hz, 2H), 7.35 (td, J=7.6, 1.5 Hz, 1H), 7.28 (d, J=7.4 Hz, 1H), 7.21 (d, J=8.6 Hz, 2H), 7.10 (t, J=7.4 Hz, 1H), 6.89 (dd, J=8.0, 1.7 Hz, 1H), 6.75 (dd, J=8.0, 4.6 Hz, 1H), 6.72 (s, 2H), 2.45-2.38 (m, 2H), 2.23-2.16 (m, 2H), 2.10-2.00 (m, 1H), 1.75-1.66 (m, 1H); LCMS: 473 [M+H].
