Procedure

A solution of 1.9 ml of methyl chlorooxalate in 10 ml of methylene chloride is added dropwise to a solution of 2.5 g of 3-aminoanisole and 1.5 ml of pyridine in 40 ml of methylene chloride in the course of 10 minutes. After stirring at room temperature for 3 hours, the mixture is poured onto water and extracted with methylene chloride. The extracts are dried over sodium sulfate and evaporated and the residue is crystallised from ether/hexane. Methyl N-(3-methoxyphenyl)-oxamate is obtained.
