Participants

Reaction Steps

6.54 g (22.1 mmol) of 3-bromo-4-chloro-5-(1-fluoropropyl)-1-nitrobenzene was dissolved in a solvent mixture comprising 30 ml of methanol and 90 ml of acetonitrile, followed by the addition of 120 ml of a 20% solution of titanium trichloride in diluted hydrochloric acid under a nitrogen stream under cooling with ice. The obtained mixture was stirred at room temperature for 3 hours and then poured into water. The resulting mixture was extratcted with ethyl acetate. The ethyl acetate phase was washed with a saturated aqueous solution of sodium hydrogen carbonate and a saturated brine successively, dried and distilled to remove the solvent. The residue was purified by silica gel column chromatography to give 5.04 g of the title compound (yield: 86%).
