Reliable quality 91-40-7 lowest price N-Phenylanthranilic acid  in bulk supply

N-phenylaminobenzoic acid, also known as vanadium reagent, is an important intermediate in the synthesis of acridine compounds. It can be obtained by coupling 2-chlorobenzoic acid and aniline.

2-chlorobenzoic acid (25.64mmol) and aniline (12.82mmol), potassium carbonate (19.23mmol) and copper powder (19.23mmol) were sequentially added to dimethylformamide (50 ml) solvent, then heated and refluxed at 130 ° C. Overnight, TLC detection (developing solvent was ethyl acetate: petroleum ether acetic acid = 1:1) the reaction was completed. The resulting reaction mixture was then cooled and filtered with diatomaceous earth, and the resulting filtrate was added to 200ml of water. The system was then adjusted to a pH of about 3 with hydrochloric acid, filtered with suction, and the resulting precipitate was dried, 2-(N-phenylamino) benzoic acid was obtained as a dark green solid powder in 50.72% yield with a melting point of 173.9 °c -178.0 °c.

2g of anthranilic acid, 3.2g of bromobenzene, 2g of potassium carbonate, 0.1g of lead powder and 12mg of nitrobenzene were mixed and heated under reflux for 3 hours. The nitro group and unreacted bromobenzene were distilled off with steam, cooled and filtered, and the filtrate was made acidic with hydrochloric acid to obtain crude N-phenyl anthranilic acid. The crude product is recrystallized from benzene and is a 3G finished product.
