Participants

Reaction Steps

To cis-(3RS,5RS)-5-hydroxy-3-piperidinecarboxylic acid sodium salt (5.2 g; 31.0 mmol) in 0.5 N NaOH (100 ml) was added benzyl chloroformate (7.0 ml; 50.0 mmol) and the reaction was allowed to stir at room temperature under N2 for 14 hours. The reaction was extracted with diethyl ether (2×50 ml), acidified with 6N HCl (pH=2) and extracted with EtOAc (4×100 ml). The combined organic extracts were dried with Na2SO4, the solvents were removed to provide the desired compound (6.2 g; 72%).
