The general procedure for the synthesis of 7-chloro-4(3H)-quinazolinone from formamidine acetate and 2-amino-4-chlorobenzoic acid was as follows: 10 g of 2-amino-4-chlorobenzoic acid (BB1) and 8 g of formamidine acetate (1.3 eq.) were added to a 100 ml eggplant flask and mixed thoroughly. The mixture was placed in a microwave reactor and reacted at 60% power for 4 min. After completion of the reaction, it was cooled to room temperature, 30 ml of water was added, stirred and the solid product was collected by filtration. The resulting product was 7-chloro-4(3H)-quinazolinone (BB2) in a yield of 10 g with 95% yield. | [References]
