2-Fluoroaniline → HCID 51254627, compound

Participants

Reaction Steps

To a solution of piperidine-1,3-dicarboxylic acid 1-tert-butyl ester 1 (1.0 g, 4.4 mmol), 2-fluoroaniline (463 μl, 4.8 mmol) in CH2Cl2 (25 ml) at 0° C. was added DCC (0.99 g, 4.8 mmol) in several portions. The mixture was stirred at room temperature overnight. The white precipitate was removed by filtration. After removal of solvent, the residue was purified by column chromatography (silica gel, hexane/ethyl acetate, 4:1) to give 3-(2-fluorophenylcarbamoyl)piperidine-1-carboxylic acid tert-butyl ester (2) as a colorless oil (1.13 g, 80%).
