Versuchsvorschrift

A mixture of 4-bromo-3-chloro-7-(2-hydroxypropan-2-yl)-9H-carbazole-1-carboxamide [Intermediate 3] (100 mg, 0.262 mmol), 8-fluoro-1-methyl-3-(RS)-(2-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)quinazoline-2,4(1H,3H)-dione [Intermediate 2] (161 mg, 0.393 mmol), tetrakis(triphenylphosphine)palladium (15 mg, 0.013 mmol) and 2 M aqueous K3PO4 (0.26 mL, 0.524 mmol) in THF (2 mL) in a pressure reaction vial was heated at 90° C. for 2.5 h. The cooled mixture was concentrated, and the residue was purified by column chromatography on silica gel (40 g), eluting with DCM-MeOH—NH4OH (gradient from 90:9:1-97:2.7:0.3). The resulting impure product was again purified by column chromatography on silica gel (40 g), eluting with EtOAc-hexanes (gradient from 50-100%), to give 3-chloro-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 (110 mg, 68% yield).
