PROCEDURE
实验过程
To a hot solution of 4.328 parts of 8-(3 -2-t-butylphenoxy -2-hydroxypropoxy)-4-oxo-4H-1-benzopyran-2carboxylic acid in 250 parts of ethanol was added a solution of 0.882 parts of sodium bicarbonate in 50 parts of water. The resulting solution was filtered and allowed to cool to give 4.0 parts of sodium 8-(3-[2-t-butylphenoxy]-2-hydroxypropoxy)-4-oxo-4H-1-benzopyran-2-carboxylate sesquihydrate after collecting and drying over phosphorus pentoxide.
