Participants

Reaction Steps

5Parts of 5-[8-allyl-5-(3-methylbutoxy)-4-oxo-4H-1-benzopyran-2-yl]tetrazole and 1.29 parts of sodium bicarbonate were mutually dissolved in 200 parts of water. To this stirred solution 1.25 parts of calcium nitrate in 100 parts of water were added. A creamy precipitate was produced. The mixture was cooled and the precipitate was collected. The compound was finely powdered, treated with boiling water, collected and dried in vacuo. 4.8 Parts of 5-[8-allyl-5-(3-methylbutoxy)-4-oxo-4H-1-benzopyran-2-yl]tetrazole as its calcium salt pentahydrate were obtained.
