Sulfuryl chloride → Ethyl 2-chloro-3-oxopentanoate

Participants

Reaction Steps

Sulphuryl chloride (286 g.) was added dropwise to a solution of ethyl 3-oxopentanoate (300 g.) in chloroform (250 ml.) at 10°-15°. Following addition the mixture was stirred overnight at room temperature, heated under reflux for 0.5 hour and cooled. After washing with water, sodium bicarbonate and water, the solution was dried (sodium sulphate), concentrated and fractionated to yield ethyl 2-chloro-3-oxopentanoate, b.p. 94°-96°/14 mm.
