Reaction Steps
A solution of 0.449 g of 1-[3-fluoro-4-(1-methylbutoxy)phenyl]ethanone in 6.8 ml of dioxane was dropped dropwise into 1.36 g of NaOH, 1.6 g of bromine in 6.8 ml of water. The mixture was stirred at room temperature for 30 minutes and then heated at 50° C. for 1 h. The excess bromide was decomposed by adding a sodium disulfite solution, and then the solution was poured into 25% strength hydrochloric acid solution and stirred for 20 minutes. The solution was extracted with ethyl acetate. The combined organic phases dried over sodium sulfate, concentrated in vacuo and purified by preparative HPLC. This resulted in the product with the molecular weight of 226.1 (C12H15FO3); MS (ESI): 227 (M+H+).
