To a solution of 2-chloro-2-ethoxyacetic acid ethyl ester (10 g, 60 mmol) in chloroform (30 mL) was added triphenylphosphine (15.7 g, 60 mmol) and stirred overnight at room temperature. The solvent was removed in vacuo, and diethyl ether was added. The solvent was again removed and dried on high vacuum to give (1,2-diethoxy-2-oxoethyl)triphenylphosphonium chloride (21 g, 82% yield) (679) as a foamy solid.
