32 mg (0.13 mmol) of 4-(1-benzofuran-4-yloxy)-3-fluorophenylamine (from example XXIII) and 28.5 mg (0.14 mmol) of 4-chloro-6-(4-pyridinyl)-2-pyrimidine-amine (from example XXIX) are suspended in 1.5 ml of water, and 19 μl of concentrated hydrochloric acid are added. The reaction mixture is heated at reflux overnight, resulting in the formation of a brown precipitate. Using 1N sodium hydroxide solution, the suspension is adjusted to pH 10. The precipitate is filtered off with suction and the filtrate is discarded. The crude product is purified by preparative HPLC.
