A solution of 100 mg 3-[2-(2,4-Dichlorophenyl)-ethoxy]-4-methoxy-benzoic acid in 2 ml DMF was activated by the addition of 53 mg carbonyldiimidazole. After stirring for 2 h at RT 90 mg of 4-Aminomethyl-piperidine-1-carboxamidine hydrochloride and 2 ml DMSO were added and the mixture was stirred overnight. Subsequent dilution with 3 ml water and filtration through a chem elut® cartridge, eluting with ethyl acetate yielded after concentration under reduced pressure a white solid. Purification by preparative HPLC (C18 reverse phase column, elution with a H2O/MeCN gradient with 0.5% TFA) and lyophilisation afforded 30 mg (20%) of the title compound as a white powder.
