Compound 2-(7-formamido-9H-carbazol-2-yloxy)ethyl 4-methylbenzenesulfonate (AD-CB-012P-WZ02039) was prepared using the same procedure for the preparation of AD-CB-012S-WZ01185) from N-(7-hydroxy-9H-carbazol-2-yl)formamide (100 mg) and ethane-1,2-diyl bis(4-methylbenzenesulfonate) (325 mg). (white solid, 22 mg, 12%). For the major rotomer: 1H NMR (400 MHz, acetone-d6) δ 10.19 (s, 1H), 9.31 (s, 1H), 8.38 (d, J=1.6 Hz, 1H), 8.11 (d, J=2.0 Hz, 1H), 7.90-7.81 (m, 4H), 7.45 (d, J=8.4 Hz, 2H), 7.19 (dd, J=8.4, 2.0 Hz, 1H), 6.95 (d, J=2.0 Hz, 1H), 6.69 (dd, J=8.4, 2.0 Hz, 1H), 4.43-4.41 (m, 2H), 4.29-4.27 (m, 2H); MS (ESI) m/z 425 (M+H+).
