Procedure

To a solution of 17.9 g of 3,3-dimethyl-2-oximinobenzodioxane and 5 drops of triethylamine was added 18.0 ml of methyl isocyanate. The reaction mixture was then left at ambient temperature for 16 hours. The reaction mixture was concentrated and filtered to yield 3,3-dimethyl-2-[O-(methylcarbamoyl)oximino]benzodioxane, m.p. 174°-176° C.
