Temperature: 50 °C

Procedure

A mixture of methyl 2-(bromoethyl)-5-chlorobenzoate (100 mg, 0.38 mmol), 2-chlorophenol (43 μL, 0.42 mmol) and potassium carbonate (105 mg, 0.76 mmol) in N,N-dimethylforamide (2 mL) was stirred at room temperature for 3 h and at 50° C. for 4 hours. Water (5 mL) was added and the mixture was extracted with diethyl ether (15 mL×2). The combined organic extracts were washed with brine (15 mL) and dried (sodium sulfate). After removal of solvent, the residue was purified by pTLC eluting with hexane/ethyl acetate (9/1) to afford 103 mg (87%) of the title compound:
