実験手順

To a solution of methyl (S)-3-{[2-(4,5-diphenyloxazol-2-yl)-2-cyclohexen-1-yl]methyl}benzoate (0.3 g) in a mixture of ethanol (8 ml) and tetrahydrofuran (5 ml) was added 1N-sodium hydroxide solution (3.5 ml). After stirring the mixture for 24 hours at the same temperature, the solvent was removed. The residue was partitioned between EtOAc and 1N-hydrochloric acid, and the organic layer was washed with brine. The dried solvent was evaporated in vacuo and the obtained solid was washed with a mixture hexane and ether to afford (S)-3-{[2-(4,5-diphenyl-oxazol-2-yl)-2-cyclohexen-1-yl]methyl}benzoic acid (0.28 g).
