실험 절차

An appropriately equipped glass reaction vessel was charged with 186.5 grams (1 mole) of 4-chlorotetrahydrophthalic anhydride and heated to 150° C. under nitrogen. Methylamine gas (32 grams, 1.03 mole) was then introduced to the reaction vessel subsurface over 30 minutes. The reaction mixture was then heated for 3 hours at 180° C. The product was then distilled to give N-methyl-4-chlorophthalimide in approximately 95% yield.
