Chloroform → 3-(4-Aminomethyl-3-chlorophenyl)-5-(3,4,5-trichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole

Participants

Reaction Steps

To a solution of 3.0 g of N-[[2-chloro-4-[5-(3,4,5-trichlorophenyl)-5-trifluoromethyl-4,5-dihydroisoxazole-3-yl]phenyl]methyl]phthalimide in 70 mL of ethanol, 1.0 mL of 80% hydrazine monohydrate was added and the resultant mixture was stirred while heating the mixture to reflux for 1 hour. After the completion of the reaction, the reaction mixture was left to be cooled down to room temperature and 100 mL of chloroform was added to the reaction mixture to filter off an insoluble substance, followed by distilling off the solvent under reduced pressure. To the resultant residue, 50 mL of chloroform was added to dissolve the residue and to filter off the resultant insoluble substance. The filtrate was washed with water (50 mL×1) and then dehydrated and dried over saturated saline and anhydrous magnesium sulfate in this order and the solvent was distilled off under reduced pressure to obtain 2.55 g of the objective substance as a yellow resinoid.
