In order to clarify in more detail the dechlorination of the chlorine-substituent in 4 (3H) -quinazolinone in the course of the quinazolinone cyclization process, some further experiments have been carried out by the modified Willgerodt-Kindler reaction condition and the modified Niementowski reaction. The results obtained proved that the dechlorination occurred at the cyclization step in the modified Niementowski reaction.
