실험 절차

(3R,4R)-1-Benzyl-4-methyl-3-pyrrolidine carboxylic acid (6.27 g) was suspended in dichloromethane (250 mL). To this suspension, cyclopropylamine (1.76 mL) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (12.2 g) were sequentially added and the mixture was stirred at room temperature for 4 hours. Subsequently, the reaction mixture was washed with water, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate: methanol=10:1) to give (3R,4R)-1-benzyl-N-cyclopropyl-4-methyl-3-pyrrolidine carboxamide (3.32 g) as white crystals.
