Reaction Steps

A solution of 1.09 g (5.96 mmol) 1-(2-fluoro-4-methoxy-3-methyl-phenyl)-ethanone was dissolved in 12 ml acetic acid and 6 ml 62% aqueous HBr. The reaction mixture was stirred 2 h at room temperature and heated to 120° C. for 6 h, cooled, diluted with ether and neutralized carefully with aqueous saturated NaHCO3 (pH=8). Extraction of the water phase with ether (two times), washing with aqueous 10% NaCl, drying (Na2SO4) and evaporation gave 0.78 g of the crude product as a dark red gum.
