Ethyl bromopyruvate → HCID 15233869, compound

Participants

Reaction Steps

The product from Example 16 (0.87 g, 3.56 mmol) was dissolved in DME (25 mL) and placed in a 100 mL flask. Ethyl bromopyruvate (0.76 g, 3.92 mmol) was added to the flask, and the reaction was allowed to stir under a N2 atmosphere for 16 h. After solvent removal in vacuo, the residue was taken up in abs EtOH (25 mL) and refluxed for 5 h. The reaction was cooled to room temperature and solvent was removed in vacuo. The residue was dissolved in aqueous K2CO3 and the product extracted with EtOAc. Purification via a chromatotron (97/2/1 CH2Cl2 /EtOH/NH4OH) produced 0.38 g (32%) of title compound.
