0.7 ml of 0.1 N NaOH is added to a suspension of 30 mg of 3-(2,1,3-benzothiadiazol-5-yl)-4-benzyl-5-hydroxy-5-(4-methoxyphenyl)-5H-furan-2-one in 1 ml of methanol and the mixture is stirred at room temperature. The solvent is removed, the residue is partitioned between water and diethyl ether, and the agueous phase is then lyophilized. Sodium 2-(2,1,3-benzothiadiazol-5-yl)-3-benzyl-4-(4-methoxyphenyl)-4-oxo-2-butenoate, FAB 453, is obtained.
