実験手順

1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (1.12 g) was added to a mixture of 4-benzyloxy-3-methoxybenzylamine hydrochloride (1.26 g), (S)-1-(t-butoxycarbonyl)pyrrolidine-3-carboxylic acid (0.97 g), triethylamine (0.82 ml) and methylene chloride (20 ml). After stirring the reaction mixture at room temperature for 20 hours, the mixture was washed with saturated ammonium chloride aqueous solution and then saturated brine, the organic layer was dried over sodium sulfate and the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (elution solvent: hexane/ethyl acetate=100/0 to 0/100 gradient) to obtain 1.42 g of t-butyl (S)-3-(4-benzyloxy-3-methoxybenzylcarbamoyl)-piperidine-1-carboxylate.
