Reaction Steps

To a stirred solution of 2.0 grams (0.006 mole) of 2-[2-chloro-4-(1,1-dimethylethoxycarbonylamino)phenyl]methyl-4,4-dimethyl-3-isoxazolidinone in 10 ml of methylene chloride was added dropwise a solution of 10 ml of trifluoroacetic acid in 10 ml of methylene chloride. Upon completion of addition the reaction mixture stirred at ambient temperature for 3.5 hours. The reaction mixture was slurried with 50 ml of water and neutralized with a saturated aqueous solution of potassium carbonate. A solid precipitate was collected by filtration to give 1.3 grams of 2-(4-amino-2-chlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone; m.p. 106°-108° C.
