Procedure

The foregoing alcohol (380 mg) is reacted with 35% HClO4 (4 ml) in CH2Cl2 (4 ml) at RT for 24 hours. The mixture is then extracted with CH2Cl2 and the combined extracts washed, dried and concentrated to dryness. The product is purified by prep. thin layer chromatography to give 4-[4-(2-chloro-4-trifluoromethylphenoxy)phenoxy]-3-oxo-1-pentene, MS m/e 396 (M+).
