2,5-Dichlorobenzoic acid → HCID 54433102, compound

Participants

Reaction Steps

Potassium fluoride (0.326 g, 5.61 mmol) was added to a mixture of the tert-butyl (S)-3-bromo-2-oxo-1-phenethylpropylcarbamate (1.00 g, 2.81 mmol) and 2,5-dichlorobenzoic acid (1.07 g, 5.61 mmol) in DMF (10 mL). The mixture was stirred for 2 hours at room temperature and then ethyl acetate (75 mL) was added. The solution was washed with 1M hydrochloric acid (20 mL), saturated aqueous sodium bicarbonate (20 mL), dried (MgSO4), filtered, and evaporated to dryness to provide crude (S)-3-tert-butoxycarbonylamino-2-oxo-5-phenylpentyl 2,5-dichlorobenzoate.
