Participants

Reaction Steps

The mixture of 0.5 g of N-(4-isocyanato-o-tolyl)-4-chlorophthalimide, 25 ml of p-dioxane and 10 ml of N hydrochloric acid is refluxed for 30 minutes and evaporated. The residue is taken up in methylene chloride, the solution washed with cold 5% aqueous sodium carbonate, dried, evaporated and the residue recrystallized from ethyl acetate, to yield the N-(4-amino-o-tolyl)-4-chlorophthalimide melting at 202°-204°.
