The reaction mixture was cooled down to 0 °C and then benzyl chloroformate (1.42 mL, 1.7 g, 10 mmol) was slowly added dropwise. After the dropwise addition, the reaction solution was stirred at room temperature for 2 hours. Upon completion of the reaction, the reaction mixture was acidified to pH ~2-3 by dropwise addition of aqueous 1N HCl. Subsequently, acetonitrile was removed by evaporation under reduced pressure, and the aqueous phase was extracted with ethyl acetate (3 x 30 mL). The organic phases were combined, washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give 1-(benzyloxycarbonyl)piperidine-4-carboxylic acid in quantitative yield, and the product was used directly in the next step of the reaction. | | References | [1] Synlett, 2017, vol. 28, # 3, p. 376 - 380
