Procedure
To a 50 ml round bottom flask fitted with a magnetic stirring bar and a reflux condensor was loaded 2-[2-bromo-4-(trifluoromethoxy)phenyl]-4,4-dimethyl-4,5-dihydro-1,3-oxazole (0.56 g, 1.66 mmol) and 10 ml 5N HCl. The reaction mixture was heated at 90° C. overnight. After cooling to room temperature, the reaction mixture was diluted with 20 ml water and extracted with 40 ml ethyl acetate. The extracts were dried over sodium sulfate, filtered and concentrated to give 0.42 g light brown solid.
