実験手順

N-Methyl-N-(1-methyl-1H-indol-2-ylmethyl)acrylamide (from Example 76 (a)) was taken up in propionitrile (50 mL). To this solution was added with stirring 2-phenylamino-5-bromopyridine (1.3 g, 5.2 mmole), DIEA (1.8 mL, 10 mmole), Pd(OAc)2 (112 mg, 05 mmole) and P(o-tol)3 (304 mg, 1.0 mmole). The reaction was purged with argon then stirred at reflux for 16 h. After cooling to room temperature the reaction was concentrated to dryness under vacuum. Flash chromatography on silica gel (5% methanol/CHCl3) followed by a second flash column on silica gel (50-70% EtOAc/CHCl3) left a residue that was triturated with EtOAc/petroleum ether. Filtration and drying under vacuum gave the title compound (1.42 g, 69%) as an off-white powder: MS (ES) m/e 396.20 (M+H)+.
