실험 절차

10% Pd/C (50.0 mg) was added to a solution of tert-butyl (1-{4-[2-(4-methyl-3-nitrophenyl)-9H-imidazo[1,2-d]pyrido[2,3-b][1,4]benzodiazepin-3-yl]phenyl}cyclobutyl)carbamate (49.1 mg, 0.0799 mmol) in MeOH (5 mL), and the mixture was stirred for 6.5 hours under hydrogen atmosphere. The catalyst was filtered off and washed with MeOH. The combined filtrate and washings were concentrated, and the residue was purified by silica gel column chromatography (EtOAc/hexane=1:2→1:1→2:1→EtOAc) to afford desired product (28.2 mg, 60.4%) as pale yellow solid. 1HNMR (CDCl3) 400 MHz δ: 8.17 (dd, J=7.8, 1.4 Hz, 1H), 8.00 (dd, J=5.0, 1.4 Hz, 1H), 7.39-7.31 (m, 2H), 7.27 (td, J=7.7, 1.5 Hz, 1H), 7.21-6.69 (m, 8H), 6.58 (dd, J=7.8, 4.6 Hz, 1H), 6.52-6.46 (m, 1H), 5.24 (br s, 1H), 3.56 (br s, 2H), 2.63-2.27 (m, 4H), 2.19-2.06 (m, 1H), 2.14 (s, 3H), 1.95-1.74 (m, 1H), 1.38 (br s, 9H).
