Procedure
4-Bromophenol, N-(2-bromoethyl)phthalimide and potassium carbonate were suspended in dimethylformamide and heated to 50° C. overnight under nitrogen. The dimethylformamide was removed under reduced pressure. The resulting residue was partitioned between ethyl acetate and water. The aqueous phase was extracted twice with ethyl acetate. The organics were combined, washed several times with brine, dried over magnesium sulfate, filtered and concentrated in vacuo. Yield: 2 g, 98%; LCMS: RT method: 2, RT: 5.33 min, MI: 382-384 [M+1].
