Versuchsvorschrift

A mixture of 4-bromo-3-cyano-7-(2-hydroxypropan-2-yl)-9H -carbazole-1-carboxamide [Intermediate 23] (0.400 g, 1.08 mmol), 8-fluoro-1-methyl-3-(2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)quinazoline-2,4(1H,3H)-dione [Intermediate 2] (0.573 g, 1.40 mmol), Cs2CO3 (0.700 g, 2.15 mmol), and dioxane (5 mL) was subjected to 3 evacuate-fill cycles with nitrogen. The mixture was treated with PdCl2(dppf) DCM adduct (0.053 g, 0.064 mmol) and subjected to 2 more evacuate-fill cycles with nitrogen. The mixture was heated at 88° C. for 2 days. The cooled mixture was diluted with EtOAc, washed sequentially with water and brine, and dried and concentrated. The residue was purified by column chromatography on silica gel, eluting with EtOAc-hexanes (sequentially 50%, 75%, 85% and 100%). The resulting impure product was purified by reverse-phase preparative HPLC to give 3-cyano-4-(3-(8-fluoro-1-methyl-2,4-dioxo-1,2-dihydroquinazolin-3(4H)-yl)-2-methylphenyl)-7-(2-hydroxypropan-2-yl)-9H-carbazole-1-carboxamide (mixture of four atropisomers) as a white solid (0.200 g, 32% yield). Mass spectrum m/z 576 (M+H)+. 1H NMR (400 MHz, DMSO-d6) δ 11.96 (s, 1H), 8.45 (s, 1H), 8.35 (br. s., 1H), 8.00-7.94 (m, 1H), 7.92 (s, 1H), 7.77-7.68 (m, 2H), 7.60-7.52 (m, 2H), 7.41 (dd, J=6.6, 2.2 Hz, 1H), 7.38-7.29 (m, 1H), 7.13 (t, J=10.1 Hz, 1H), 6.85 (t, J=8.1 Hz, 1H), 5.05 (d, J=2.0 Hz, 1H), 3.74 (dd, J=8.1, 2.6 Hz, 3H), 1.73 (s, 3H), and 1.48-1.43 (m, 6H).
