Versuchsvorschrift

To a solution of 0.55 g of (3R)-3-aminomethyl-1-(tert-butoxycarbonyl)piperidine and 1.1 g of 3-(2-{(3,3,3-triphenylpropanoyl)amino}acetylamino)propionic acid in 10 ml of N,N-dimethylformamide, 0.52 g of 1-hydroxybenzotriazole monohydrate and 0.75 g of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide monohydrochloride were successively added at room temperature, and stirred for 2 hours at the same temperature. Then 2.0 ml of triethylamine and 10 ml of chloroform were added at room temperature, followed by an hour's stirring. The reaction liquid was distilled off under reduced pressure, diluted with ethyl acetate, washed successively with saturated aqueous sodium bicarbonate solution, 10% aqueous citric acid solution and saturated saline solution, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the residue was purified by means of silica gel column chromatography (eluting solvent: chloroform/methanol=19/1) to provide 1.41 g of the title compound.
