実験手順

(3R,4R)-1-Benzyl-4-methyl-3-pyrrolidinecarboxylic acid (6.27 g) was suspended in dichloromethane (250 mL). To this suspension, cyclopropylamine (1.76 mL) and hydrochloric acid 1-ethyl-(3-dimethylaminopropyl)carbodiimide (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, was dried over anhydrous sodium sulfate, and was then concentrated under reduced pressure. The resulting residue was purified on a silica gel column (ethyl acetate: methanol=10:1) to give 3.32 g of (3R,4R)-1-benzyl-N-cyclopropyl-4-methyl-3-pyrrolidinecarboxamide as a white crystal.
