Versuchsvorschrift
Compound 54 was prepared from 2,3,4,9-tetrahydro-2,4,9,10-tetraazacyclohepta[def]fluoren-8(1H)-one and 3,3-dimethylbutanal according to the procedures similar to those for Compound 44. 1H NMR (DMSO-d6) δ 11.9 (s, 1H), 9.89 (s, 1H), 7.48 (d, 1H, J=7.8 Hz), 7.43 (d, 1H, J=7.2 Hz), 7.13 (dd, 1H, J=7.2, 7.8 Hz), 3.81 (br s, 2H), 3.29 (br s, 2H), 2.57-2.58 (m, 2H), 1.43-1.46 (m, 2H), and 0.91 (s, 9H). MS (ESI) m/e [M+1]+ 311.
