Procedure

Step 2 A mixture of 7-(2-hydroxypropan-2-yl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-9H-carbazole-1-carboxamide (ca. 60% purity, 35 mg, 0.053 mmol), N-(3-bromo-2-methylphenyl)-8-fluoroquinazolin-4-amine (Intermediate 32-7, 17.69 mg, 0.053 mmol), and 2 M aqueous sodium carbonate (0.067 mL, 0.133 mmol) in toluene (0.8 mL) and ethanol (0.200 mL) was purged with argon, treated with tetrakis(triphenylphosphine)palladium (3.1 mg, 0.003 mmol) and heated at 90° C. in a sealed tube for 16.5 h. The mixture was cooled to rt and concentrated. The residue was purified by preparative HPLC and the appropriate effluent fractions were treated with NaHCO3 (aq) and partially concentrated at rt. The resulting aqueous suspension was filtered and the precipitate was washed with water and dried to provide 4-(3-(8-fluoroquinazolin-4-ylamino)-2-methylphenyl)-7-(2-hydroxypropan-2-yl)-9H-carbazole-1-carboxamide as a white solid (18.0 mg, 61%). 1H NMR (400 MHz, DMSO-d6) δ 11.41 (1H, s), 10.08 (1H, s), 8.56 (1H, s), 8.35 (1H, d, J=8.4 Hz), 8.16 (1H, br. s.), 7.99 (1H, d, J=7.9 Hz), 7.87 (1H, s), 7.70 (1H, dd, J=10.2, 8.3 Hz), 7.60 (1H, td, J=8.1, 5.2 Hz), 7.42-7.54 (3H, m), 7.28 (1H, dd, J=7.3, 1.3 Hz), 7.11 (2H, s), 7.01 (1H, d, J=7.7 Hz), 5.00 (1H, s), 1.85 (3H, s), 1.49 (6H, s). Mass spectrum m/z 520.1 (M+H)+.
