実験手順

35 mg (0.14 mmol) of 3-fluoro-4-[(3-methyl-1H-pyrrolo[2,3-b]pyridin-4-yl)oxy]aniline and 24.5 mg (0.15 mmol) of 4,6-dichloropyrimidine-2-amine are suspended in 2.5 ml of water. 17 μl (0.18 mmol) of 37% strength hydrochloric acid are added, and the mixture is heated at reflux overnight. Using 1N aqueous sodium hydroxide solution, the pH is adjusted to 10, resulting in the precipitation of crystals. The crystals are filtered off with suction and purified by column chromatography on silica gel (mobile phase: dichloromethane:methanol (7N ammonia) 100:5).
