Reaction Steps

To a stirred mixture of 0.5 parts of N,N,N-triethylbenzenemethanaminium chloride, 4 parts to sodium hydroxide and 40 parts of water were added dropwise 16 parts of 2-chloro-4-methoxyphenol and 18.2 parts of 1,2-dibromoethane at 50° C. Upon complete addition, stirring was continued overnight at 50° C. The reaction mixture was poured into water and the product was extracted with a mixture of 2,2'-oxybispropane and dichloromethane. The extract was dried, filtered and evaporated, yielding 14 parts (52.7%) of 1-(2-bromoethoxy)-2-chloro-4-methoxybenzene as a residue (int. 5).
