Water → Ethyl 2-chloro-3-(2-nitrophenyl)-3-oxopropanoate

Participants

Reaction Steps

To a solution of ethyl 3-(2-nitrophenyl)-3-oxopropanoate (2.0 g, 8.4 mmol) in diethyl ether (50 mL), was added sulfuryl chloride (1.37 g, 10 mmol) at 0° C., and the mixture was stirred for 3 h at rt. To the reaction mixture were added water (200 mL) and EtOAc (100 mL), and the mixture was stirred for 30 min. The organic layer was washed with brine (10 mL) and dried over anhydrous magnesium sulfate. Insoluble materials were removed by filtration and the filtrate was concentrated under reduced pressure to give the title compound (1.7 g, 75%) as colorless oil.
