Reaction Conditions

Reaction Steps

2-Nitrophenol (70 mmol ), 1-bromo-3-chloropropane (360 mmol), potassium carbonate (water free, 110 mmol), potassium iodide (2 mmol) and tetrabutyl-ammonium bromide (1 mmol) are suspended in acetone (130 ml) and heated up to 50° C. and the mixture is then stirred at this temperature for 30 hours. After cooling down to RT the solid material is filtered off and the filtrate is evaporated. The excess of 1-bromo-3-chloropropane is distilled of under vacuum (70° C.). A yellow-orange oil with Rf=0.55 (hexane/ethyl acetate=2:1) is obtained, which is used in the next step without further purification.
