MALONIC ACID DIPHENYL ESTER

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Malonic acid (11 g, 106 mmol) was mixed with phenol (20 g, 212 mmol) at 0° C. under nitrogen and phosphorus oxychloride (11.5 mL, 123 mmol) was added dropwise to the solid mixture. The resulting mixture was stirred at 0° C. for 5 mins, and then heated at reflux for 5 h, causing the solid to melt and an orange solution to form. The reaction was cooled to room temperature, and then poured onto 100 mL water and extracted with diethyl ether (3×75 mL). The combined organics were washed with brine, dried over MgSO4, concentrated in vacuo to an orange oil of the title compound. (27 g, 99%). heated at reflux for 5 h an orange solution to form The reaction was cooled to room temperature extracted with diethyl ether (3×75 mL) The combined organics were washed with brine dried over MgSO4 concentrated in vacuo to an orange oil of the title compound
