Reaktionsschritte

To a solution of 10.5 mg (0.08 mmol) of 2-pyrazinecarboxylic acid in 1 ml of DMF were added 27.9 mg (0.085 mmol) TOTU. After 15 min at room temperature 55 mg (0.085 mmol) of 4-Aminomethyl-N-(4-amino-2-methyl-quinolin-6-yl)-benzamide and 39 mg (0.34 mmol) of N-ethylmorpholine were added. After 24 h stirring at room temperature the solution was evaporated and the residue was treated with acetonitrile and water containing 0.005% trifluoroacetic acid. The precipitate was filtered to give 36.7 mg (71%) of the title compound.
