Procedimiento

To a suspension of 25.0 g (0.17 mol) of phthalic anhydride in 200 ml of water was added 30 g (0.38 mol) of a 40% aqueous solution of methylamine. The mixture was heated at reflux for four hours, after which approximately 50 ml of the aqueous amine was removed by distillation and the mixture allowed to cool. The resultant precipitate was collected by filtration to yield 10.3 g of N-methylphthalimide (cyclic imide (b)(4)).
