Procedure
A mixture of 11.11 parts of 4-oxo-7-(3-[2-propylphenoxy]propoxy)-4H-1-benzopyran-2-carboxylic acid and 2.4 parts of sodium bicarbonate in 200 parts of water was heated to effect solution. The solution was filtered and freeze dried to yield 11.5 parts of sodium 4-oxo-7-(3-[2-propylphenoxy]propoxy)-4H-1-benzopyran-2-carboxylate.
