실험 절차

To a mixture of 4-[4-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-3-methoxy-2-pentenoyl chloride (10 mm.) and ether (10 ml.) is added methyl mercaptan (12 mm.) and pyridine (1 ml.) at about -20°. The mixture is stirred for about 30 minutes and then allowed to rise to about 0° and stand for about 2 hours. The mixture is then diluted with ether and water and the ether phase separated, washed, dried and solvent removed to give the methylthiol ester of 4-[4-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-3-methoxy-2-pentenoic acid.
