Procedure

To a solution of 3-methyl-4-nitrophenol (45 g, 0.294 mol) in dimethylformamide (270 mL) there were added 1-bromodecane (65 g, 0.294 mol) and potassium carbonate (121.8 g, 0.882 mol). The reaction mixture was heated to 115° C. and stirred at that temperature for 48 hours. The reaction mixture was cooled and poured into water (4 L), stirred for 0.5 hour and extracted with two portions of ethyl acetate (1.5 L and 600 mL). The combined organic extracts were washed with 5% aqueous solution sodium bicarbonate (1 L), water (1 L and 0.5 L), dried over sodium sulfate and concentrated to give the crude product (90 g, 0.294 mol, 100% yield). This product was used in the next step without purification.
