실험 절차

A solution of N-methyl-N-(2-methyl-1H-indol-3-ylmethyl)acrylamide (1.18 g, 6.5 mmole), 2-amino-5-bromopyrimidine (0.5 g, 2.9 mmole), Pd(OAc)2 (0.11 g, 0.49 mmole), tri-ortho-tolylphosphine (0.17 g, 0.55 mmole), and diisopropylethylamine (1.5 mL, 8.6 mmole) in propionitrile (100 mL) and DMF (10 mL) was heated at reflux overnight. The dark mixture was filtered through celite®, and the filtrate was concentrated. Flash chromatography on silica gel (9:1 CHCl3/CH3OH containing 5% NH4OH) gave the title compound (1.2 g, 65%): MS (ES) m/e 372 (M+H)+.
