Procedure

90 mg (0.2 mmol) of 2-[(2-bromo-pyridin-4-ylmethyl)-amino]-N-(3-trifluoromethyl-phenyl)-benzamide and 23 mg (0.24 mmol) of methanesulfonic acid amide are introduced into 5 ml of dioxane and mixed in succession with 4 mg (0.02 mmol) of copper(I) iodide, 85 mg (0.4 mmol) of potassium phosphate and 2 mg (0.02 mmol) of ethylenediamine. After 1 hour of stirring at a bath temperature of 120° C., it is diluted with 20 ml of water and concentrated by evaporation. It is then made alkaline with ammonia and shaken out three times with 25 ml each of ethyl acetate. The collected organic phase is washed with water, dried, filtered and concentrated by evaporation. The residue is made crystalline with ethyl acetate and a little hexane, stirred and suctioned off. 24 mg (26% of theory) of 2-[(2-methanesulfonyl-amino-pyridin-4-ylmethyl)-amino]-N-(3-trifluoromethyl-phenyl)-benzamide with a melting point of 214.5° C. is obtained.
