1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → (2S,5R)-6-(benzyloxy)-7-oxo-N-(2-oxopiperidin-1-yl)-1,6-diazabicyclo[3.2.1]octane-2-carboxamide

Participants

Reaction Steps

To a mixture of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.250 g, 0.905 mmol) in DCM (15.0 mL) were added 1-aminopiperidin-2-one 256 (31 mg, 0.27 mmol),), HOBt (38 mg, 0.27 mmol), DMAP (32 mg, 0.27 mmol) and EDCI (53 mg, 0.27 mmol). The mixture was stirred at room temperature for 48 h and purified by column to afford 257 as foam (55 mg, 82%).
