実験手順

Methyl 5-amino-2-(3-hydroxyphenyl)-6-(1-(phenylsulfonyl)-1H-indol-4-ylamino)pyrimidine-4-carboxylate. Methyl 5-amino-2-chloro-6-(1-(phenylsulfonyl)-1H-indol-4-ylamino)pyrimidine-4-carboxylate (0.31 g, 0.68 mmol), 3-hydroxyphenyboronic acid (0.14 g, 1.0 mmol), palladium (II) acetate (30 mg, 0.14 mmol), dicyclohexyl(2′,6′-dimethoxybiphenyl-2-yl)phosphine (60 mg, 0.14 mmol), and potassium phosphate (0.36 g, 2.1 mmol) were reacted together according to General Procedure E. The reaction was diluted with EtOAc (40 mL) and washed with 5% HCl (aq, 40 mL). The organic layer was separated, dried over sodium sulfate, filtered, and concentrated. The crude residue was subjected to silica gel chromatography (50% Hexanes in EtOAc). Concentration of the desired fractions afforded the title compound (0.1 g, 0.19 mmol, 28%). MS (ESI) m/z 516.3[M+1]+.
