Participants

Reaction Steps

To a solution of 21 g of 4-aminomethyl-piperidine-1-carboxylic acid tert-butyl ester in 100 mL of ethyl acetate cooled to 0° C. was added 100 mL of saturated sodium carbonate and 17 g of benzyl chloroformate. The solution was stirred for 3 h, then separated. The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. Drying under vacuum gave the product as an oil:
