Procedure

Step 1 A solution of 4-(3-(4-fluorobenzamido)-2-methylphenyl)-7-(hydroxymethyl)-9H-carbazole-1-carboxamide (Example 31-4, 0.54 g, 1.155 mmol) in THF (38.5 mL) was treated with 1,1,1-tris(acetyloxy)-1,1-dihydro-1,2-benziodoxol-3-(1H)-one (Dess-Martin periodinane, 0.784 g, 1.848 mmol) at rt and the mixture was stirred for 2 h. The mixture was partitioned between NaHCO3 (aq) and EtOAc. The organic phase was washed with brine, dried and concentrated. The residue was triturated with methanol and the solid was collected by filtration and dried to provide 4-(3-(4-fluorobenzamido)-2-methylphenyl)-7-formyl-9H-carbazole-1-carboxamide as an orange solid (458 mg, 85%). 1H NMR (400 MHz, DMSO-d6) δ 11.98 (1H, s), 10.16 (1H, s), 10.03 (1H, s), 8.23-8.32 (2H, m), 8.05-8.14 (3H, m), 7.60 (1H, br. s.), 7.49-7.55 (1H, m), 7.39-7.49 (2H, m), 7.32-7.39 (2H, m), 7.21-7.27 (1H, m), 7.09 (2H, t, J=8.1 Hz), 1.88 (3H, s). Mass spectrum m/z 466.3 (M+H)+.
