Preparation of Benzoic acid, 2-amino-3,5-dibromo-: it can be prepared by methyl o-aminobenzoate through bromination reaction. Mix methyl o-aminobenzoate with hydrochloric acid in the reactor by stirring at first. Then cool the mixture to 5-15 °C. Next, add bromide-hydrochloric acid mixture into the reactor. Then the reaction should react for 1 hour below the temperature of 15 °C. And then after a series of neutralization by sodium hydroxide, filtration, washing and drying at low temperature you can get the desired product.

Uses of Benzoic acid, 2-amino-3,5-dibromo-: it can react with formamide to get 6,8-dibromo-3H-quinazolin-4-one. This reaction will need reagent montmorillonite K-10. The reaction time is 4 minutes with microwave irradiation. The yield is about 51%.
