Triethylamine → HCID 53255592, compound

Participants

Reaction Steps

To a solution of 4-aminopiperidine-1-carboxylic acid tert-butyl ester (400 mg, 200 mmol) in anhydrous dichloromethane (14 mL) under argon was added triethylamine (340 μL, 2.4 mmol) and the solution cooled in an ice bath. 2-Nitrophenylsulfonyl chloride (443 mg, 2.0 mmol) was added and the reaction allowed to stir at rt for 16 h. The crude solution was washed with water (2×30 mL) before removing the solvent in vacuo. The crude material was purified by chromatography using ethyl acetate/petroleum ether (30-60%) as the eluent to give the title compound as an off-white powder. δH (d6 DMSO): 8.43 (2H, m), 8.17 (1H, s), 8.09 (2H, m), 3.80-3.69 (2H, m), 3.31-3.23 (1H, m), 2.86-2.69 (2H, m), 1.63-1.51 (2H, m), 1.39 (9H, s), 1.29-1.17 (2H, m).
