Procedure

A 3.04 g portion of methyl 4-carboxymethylphenylacetate, prepared above, was dissolved in 50 mL of anhydrous tetrahydrofuran. After the addition of2.5 mL oxalyl chloride, the mixture was stirred for 4 hours. The solvents were evaporated under a stream of dry nitrogen as the flask was warmed to 45° C. Any remaining solvent or oxalyl chloride was then removed under high vacuum; the product was used without further purification.
