Versuchsvorschrift

A solution of 2,4-dimethyl-nicotinic acid (54 mg, 0.35 mmol) in SOCl2 (˜2 mL, excess) was heated to 80° C. for 4 hours. The condenser was removed and the mixture was flushed with N2 at 80° C. for ˜5 minutes and then dried in vacuo for 10 minutes. The resulting syrup was dissolved in CH2Cl2 (2.4 mL) and added to a stirring mixture of (4-aminomethyl-benzyl)-(1H-benzoimidazol-2-ylmethyl)-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (187 mg, 0.47 mmol), Et3N (0.33 mL, 2.35 mmol) and a catalytic amount of DMAP. The reaction mixture was stirred overnight at room temperature. Purification of the crude yellow foam (240 mg) by radial chromatography on silica gel (2 mm plate, CH2Cl2/MeOH/NH4OH, 100:2:1) followed by radial chromatography on silica gel (1 mm plate, EtOAc/MeOH/NH4OH, 400:3:3) afforded the desired amide (61 mg, 33%) as a white foam.
