Triethylamine → HCID 69313663, compound

Participants

Reaction Steps

2.00 g (12.0 mmol) of benzyloxyacetic acid was dissolved in 40 mL of dichloromethane and 2.77 g (14.4 mmol) of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, 2.21 g (14.4 mmol) of 1-hydroxybenzotriazole 1 hydrate, 2.52 mL (18.1 mmol) of triethylamine and 2.52 g (13.2 mmol) of 4-amino-1-benzylpiperidine were added thereto under ice-cooling, followed by stirring of the mixture at room temperature for 18 hours. Dichloromethane was added to the reaction mixture and the mixture was washed successively with a saturated aqueous sodium hydrogencarbonate solution, water and a saturated NaCl solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure and the obtained residue was purified by silica gel chromatography (eluting solvent: ethyl acetate/methanol=100/0-90/10) to obtain 2.82 g (yield: 69%) of the title compound as a white solid.
