実験手順
100 mg (0.23 mmol) of 2-[(2-bromopyridin-4-ylmethyl)-amino]-N-(3-isoquinolinyl)-benzamide is heated in 1 ml of dioxane with 89 mg (0.28 mmol) of cesium carbonate, 24 mg (0.69 mmol) of butyramide, 4.7 mg (0.0046 mmol) of dipalladium-tribenzylidene acetone and 7.9 mg (0.014 mmol) of Xanthphos under a cover gas and in a moisture-free environment for 25 hours to a bath temperature of 90° C. It is then mixed with 20 ml of methylene chloride, suctioned off and concentrated by evaporation. The residue is chromatographed on silica gel first with hexane, then with hexane:ethyl acetate=8:2 and then with hexane:ethyl acetate=1:1 as an eluant. 45 mg (42% of theory) of 2-[(2-butyrylamino-pyridin-4-ylmethyl)-amino]-N-(3-isoquinolinyl)-benzamide with a melting point of 173° C. is obtained.
