This ester was hydrolysed by heating under reflux with 30 mls of 10% sodium carbonate solution and 30 mls of ethanol for one hour. The solution was acidified to give a solid which was crystallised from ethanol three times to give 1.4g of 4-(7-[3-(4-acetyl-3-hydroxy-2-propylphenoxy)-2-hydroxypropoxy] -4-oxo-8-propyl-4H-1-benzopyran-2-yl)benzoic acid, melting point, 204°-206°C.
