4-Piperidinecarboxylic acid → 1-Carbobenzoxy-4-piperidinecarboxylic Acid

Participants

Reaction Steps

Triethylamine (8.1 mL, 58 mmol) was added to a solution of piperidine-4-carboxylic acid (5 g, 40 mmol) and benzyl chloroformate (7.9 g, 46 mmol) in dichloromethane (100 mL) in an ice-water bath. After being stirred overnight, the solution was washed with concentrated HCl and brine, dried over Na2SO4 and concentrated. Chromatography on silica gel gave the title compound (10 g) as an oil. MS (M+H) 264.2.
