6-BROMO-2-METHYL-3,4-DIHYDROQUINAZOLIN-4-ONE Use and Manufacturing
The bromoanthranilic acid was refluxed in liquid ammonia (10 mL/g) for 1 h. The solution was then evaporated to low bulk and the residue mixed with acetic anhydride (2 mL/g) and refluxed 4 h. Water was added, the mixture boiled for 30 min and 20percent sodium hydroxide sol. was then added until a clear solution formed. Ammonium carbonate was added to the hot solution until a precipitate formed. The mixture was held at 4° C. for 16 h before the precipitate was filtered out, washed with water and dried in vacuum (yield 60percent)
