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, 0.090 mmol), isoquinolin-6-ylboronic acid (31 mg, 0.18 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (6 mg, 0.09 mmol), and 2M Na2CO3 aq. (0.090 mL, 0.18 mmol) in DMF (2.5 mL) was treated with microwave (160° C. for 1 hour). The mixture was diluted with AcOEt, washed with water(×3), brine, dried over Na2SO4, then filtrated through Celite pad. The filtrate was concentrated and the residue was purified by preparative thin-layer chromatography (n-hexane/AcOEt=1:4) to afford the desired product (40 mg, 74%) as a white solid. 1HNMR (CDCl3) 400 MHz δ: 9.17 (s, 1H), 8.45 (d, J=6.3 Hz, 1H), 8.22 (dd, J=8.0 Hz and 1.7 Hz, 1H), 8.13-8.11 (m, 1H), 8.04 (dd, J=4.0 Hz and 1.1 Hz, 1H), 7.82-7.73 (m, 2H), 7.54 (d, J=5.7 Hz, 1H), 7.41 (dd, J=8.6 Hz and 1.7 Hz, 2H), 7.33 (td, J=8.0 Hz and 1.7 Hz, 1H), 7.21-7.17 (m, 2H), 6.97 (d, J=6.9 Hz, 1H), 6.84 (d, J=7.4 Hz, 1H), 6.62 (dd, J=8.0 Hz and 5.2 Hz, 1H), 6.27 (s, 1H), 5.16 (br s, 1H), 2.60-2.52 (m, 2H), 2.52-2.30 (m, 2H), 2.23-2.13 (m, 1H), 1.96-1.88 (m, 1H), 1.39 (br s, 9H).
