Participants

Reaction Steps

To a solution of 4.93 g of 8-allyl-5-(3-methyl-n-butoxy)-4-oxo-4H-1-benzopyran-2-carboxylic acid sodium salt in 50 parts of water was added a saturated solution of 1.2 parts of calcium nitrate in water. The resulting calcium salt was filtered off, washed with water and dried to give 5 parts of 8-allyl-5-(3-methyl-n-butoxy)-4-oxo-4H-1-benzopyran-2-carboxylic acid calcium salt monohydrate as a white solid.
