Reaktionsschritte

4.5 ml of hexamethyldisilazane (22 mmoles) were added to a refluxing mixture of 5.0 g (30.1 mmoles) of 4-nitrobenzamide, 100 mg (0.5 mmole) of 1.8-naphthalimide and 20 ml of butyl acetate and the calculated amount of ammonia was evolved after refluxing for 35 minutes. The same experiment without catalyst was carried out and only 16% of the theoretical amount of ammonia was evolved after refluxing for 15 minutes. After refluxing for 1 hour, 83% of that amount of evolved.
