To a mixture of 4-nitrophenol (150 g, 1.079 moles), potassium carbonate (600 g, 4.341 moles) and sodium iodide (10 g, 66.7 mmol) in anhydrous acetone (2.1 L) was added methyl 6-bromohexanoate (156 g, 746.41 mmol) and heated to reflux for 48 hours. Acetone was distilled off and water (2 L) was added. Crude 39 was filtered, dried and recrystallised from a mixture of ethyl acetate:hexane (1:6) to get pure 39 (130 g, 45.1%) as a white powder. M.p: 84.5.5-86.6° C.
