The reaction mass was poured into water, neutralized with a saturated aqueous sodium hydrogen carbonate solution and filtered to remove precipitated iron hydroxide. The filtrate was extracted with ethyl acetate, washed with a saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain 0.95 g of the desired product as oil. Yield was 85%.
