Participants

Reaction Steps

To an aqueous 2.5% acetic acid solution (19 ml) was added an iron powder (10-20 mesh; 1.89 g), followed by a suspension of 5-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methylnitrobenzene (4.62 g) obtained by Reference Production Example 12 in ethanol (29 ml) at 75° C., and then the mixture was stirred at the same temperature for 15 minutes. To the mixture was further added an iron powder (1.80 g) at the same temperature, and the mixture was stirred at the same temperature for 1 hour. After cooling to room temperature, the reaction mixture was filtrated and washed with ethyl acetate. Then, the filtrate was extracted with an aqueous saturated sodium hydrogen carbonate solution and ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography to obtain 5-[5-(3,5-dichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazol-3-yl]-2-methylaniline (3.18 g).
