Reaction Steps
A solution of N-Boc-L-proline 0.645 g (3 mmol), 1-benzylpiperazine 0.528 g (3 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC) 1.152 g (6 mmol) and catalytic amount of 4-(dimethylamino) pyridine in methylene chloride (50 ml) was stirred at room temperature overnight. The reaction mixture was concentrated and applied to flash column chromatography using methylene chloride and methanol (100:5) as eluents to give 1.01 g of desired product in 90% yield.
