Versuchsvorschrift

A mixture of 3-{4-(4-chlorophenyl)-2-[2-(methylsulfonyl)-1H-imidazol-1-yl]-5-oxazolyl}propionic acid (50 mg), 1-hydroxy-7-aza-1H-1,2,3-benzotriazole (41 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (46 mg), 4-[(1-methyl-4-piperidinyl)methyl]piperazine (60 mg) and N,N-dimethylformamide (0.5 ml) was stirred overnight at room temperature. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was concentrated, introduced into preparative HPLC and purified. Ethyl acetate was added to the obtained oil and the mixture was washed with saturated aqueous sodium hydrogen carbonate. A 4N hydrochloric acid ethyl acetate solution was added to the ethyl acetate layer and the mixture was concentrated to give 1-(3-{4-(4-chlorophenyl)-2-[2-(methylsulfonyl)-1H-imidazol-1-yl]-5-oxazolyl}propanoyl)-4-[(1-methyl-4-piperidinyl)methyl]piperazine 3 hydrochloric acid (65.0 mg, yield 66%).
