実験手順

To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.17 g, 0.615 mmol) in dry DCM (10 mL) were added tert-butyl 4-aminopiperazine-1-carboxylate 205 (0.19 g, 0.923 mmol), 1-hydroxybenzotriazole (0.125 g, 0.923 mmol), 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.177 g, 0.923 mmol) and 4-dimethylaminopyridine (0.113 g, 0.923 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight, and then concentrated under vacuum. The residue was purified by column chromatography to give tert-butyl 4-({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)piperazine-1-carboxylate 206 (0.25 g, 88%) as a clear thick oil.
