실험 절차

A mixture of (S)-5-bromo-6-chloro-2-(2-hydroxypropan-2-yl)-2,3,4,9-tetrahydro-1H-carbazole-8-carboxamide [Intermediate 31] (100 mg, 0.259 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] (112 mg, 0.272 mmol), Cs2CO3 (169 mg, 0.519 mmol) and PdCl2(dppf) DCM adduct (16.9 mg, 0.021 mmol) in THF (4.3 mL) and water (1.1 mL) was heated at 50° C. for 17.5 h. The cooled mixture was diluted with EtOAc, washed sequentially with water and brine, dried and concentrated. The residue was purified by column chromatography on silica gel (24 g), eluting with EtOAc-hexanes (gradient from 50-80%). The impure product was further purified by preparative HPLC to give 6-chloro-5-(3-(8-fluoro-1-methyl-2,4-dioxo-1,2-dihydroquinazolin-3(4H)-yl)-2-methylphenyl)-2-(S)-(2-hydroxypropan-2-yl)-2,3,4,9-tetrahydro-1H-carbazole-8-carboxamide (mixture of four atropisomers) (76 mg, 50% yield).
