Reaction Steps

4-Fluoro-piperidine-1,4-dicarboxylic acid 1-tert-butyl ester 4-ethyl ester (1.8 mmol, 0.5 g) was taken in 7M NH3 in MeOH (5 mL) and stirred at room temperature for 12 h in a sealed vial. All volatiles were removed under reduced pressure to provide 4-carbamoyl-4-fluoro-piperidine-1-carboxylic acid tert-butyl ester as white solid.
