To a solution of ethyl (R)-{3-{[2-(4,5-diphenyloxazole-2-yl)-1-hydroxy-2-cyclohexen-1-yl]methyl}phenoxy}acetate (7.8 g) in a mixture of ethanol (50 ml) and THF (50 ml) was added 1N-NaOH solution (15.3 ml) at room temperature. After being stirred for 4 hours at the same temperature, the mixture was evaporated. The residue was washed with diethyl ether to afford sodium (R)-{3-{[2-(4,5-diphenyloxazol-2-yl)-1-hydroxy-2-cyclohexen-1-yl]methyl}-phenoxy}acetate(6.7 g).
