실험 절차

To a solution of 1.84 g of 3-(benzyloxycarbonyl)amino-N-({(3R)-1-(tert-butoxycarbonyl)-3-piperidyl}methyl)propanamide in 2 ml of chloroform, 2 ml of trifluoroacetic acid was added at room temperature, followed by an hour's stirring at the same temperature. The reaction liquid was distilled off under reduced pressure, and the residue was rendered basic with 4N aqueous sodium hydroxide solution. Extracting the product with chloroform, the product was dried over anhydrous sodium sulfate. Upon distilling the solvent off under reduced pressure, 1.26 g of the title compound was obtained.
