Procedure

30 g of 6-phenoxymethylpyridine-2,3-dicarboxylic acid are added to a mixture of 100 ml of dimethoxyethane, 28 ml of acetic anhydride and 15 ml of pyridine while stirring and the reaction mixture is further stirred for one hour at room temperature. The whole is then concentrated by evaporation under a high vacuum. The above anhydride remains in the form of a light-coloured oil.
