Reaction Steps

To a solution of N-t-butoxycarbonyl-(S)-2-amino-5-iodopentanoic acid benzyl ester(J.Org. Chem. 1998, 7875-7884)(100.8 mg, 0.23 mmol) in N,N-dimethylformamide (0.25 mL) was added piperidine (41.5 mg, 0.49 mmol) and the mixture was stirred for 3 hours at room temperature. To the reaction mixture was added chloroform (30 mL) and the mixture was washed with saturated aqueous sodium hydrogencarbonate solution (3×3 mL). The organic phase was dried over anhydrous sodium sulfate and concentrated under vacuum to obtain crude N-t-butoxycarbonyl-(S)-2-amino-5-(1-piperidinyl)pentanoic acid benzyl ester(83.8 mg) as a colorless oily material.
