Reaction Steps

A mixture of p-chlorophenol (621 mg, 4.83 mmol), ethyl 1-bromocyclobutanecarboxylate (1.0 g, 4.83 mmol) and potassium carbonate (1.33 g, 9.66 mmol) in DMF (14.5 ml) was stirred and heated to about 55-60° C. under a nitrogen atmosphere for about 18 hours. The solvent was removed under high vacuum, the residue was taken up in diethyl ether (50 ml) and was washed with water and brine (15 ml each). The organic layer was dried (MgSO4), and filtered. The solvent was removed under vacuum and the residue was purified by flash column chromatography on silica gel using hexanes/ethyl acetate (2:1) as the mobile phase to provide 320 mg (26%) of the title compound. MS (DCI): m/z 272 (M+NH4)+.
