실험 절차

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.150 g, 0.543 mmol, US 2005/20572 A1) in DCM (4.0 mL) were added tert-butyl 4-[2-(aminooxy)ethoxy]piperidine-1-carboxylate 71 (0.240 g, 0.543 mmol), 1-hydroxybenzotriazole (0.110 g, 0.814 mmol) and 1-ethyl-(3-dimethylamino-propyl) carbodiimide hydrochloride (0.156 g, 0.814 mmol) sequentially at room temperature. The mixture was stirred at room temperature for 16 h, diluted with DCM, washed with water, brine, dried over sodium sulfate and concentrated to provide a residue which was subjected to chromatography to give 72 (0.276 g, 98%) as a colorless foam.
