Procedure

0.500 g (1.6 mmol) of 2-[(2-bromo-pyridin-4-ylmethyl)-amino]-benzoic acid, 0.471 g (3.2 mmol) of 2-methyl-2H-indazol-6-ylamine, 0.4 ml (3.68 mmol) of N-methylmorpholine and 0.729 g (1.92 mmol) of O-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluroniumhexafluorophosphate (HATU) in 25 ml of dimethylformamide are stirred for 16 hours at room temperature. The dimethylformamide is drawn off in an oil pump vacuum. The remaining residue is drawn off in saturated sodium bicarbonate solution. It is extracted three times with ethyl acetate, and the combined organic phases are dried, filtered and concentrated by evaporation. The residue is chromatographed on silica gel with a gradient that consists of hexane:acetone=100:0 to 50:50 as an eluant. 0.669 g (96% of theory) of 2-[(2-bromo-pyridin-4-ylmethyl)-amino]-N-(2-methyl-2H-indazol-6-yl)-benzamide is obtained in the form of a beige foam.
