Procedure

Combine t-butyl diethylphosphonodibromoacetate (75.6 g, 184 mmol) and isopropanol (190 mL). Cool to 0° C. Add a solution of tin (II) chloride (33.2 g, 175 mmol) in water (190 mL). After the addition is complete, warm to ambient temperature. After 1 hour, extract the reaction mixture three times with chloroform. Combine the organic layers and extract with water, dry over MgSO4, filter, and evaporate in vacuo to give the title compound.
