Procedure

To a stirred solution of 1.4 grams (0.06 mole) of 2-(4-amino-2-chlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone in 25 ml of chloroform, under an argon atmosphere, was added dropwise 5 ml of methyl isocyanate. Upon completion of addition the reaction mixture stirred at ambient temperature for 16 hours. The reaction mixture was concentrated under reduced pressure to a residual solid. The solid was recrystallized from ethanol to give 1.4 grams of 2-[2-chloro-4-(methylaminocarbonylamino)phenyl]methyl-4,4-dimethyl-3-isoxazolidinone; m.p. 227°-229° C.
