2-Amino-5-fluorobenzoic acid Chemical Properties, Uses, Production

Chemical Properties

white to light yellow crystal powder

Uses

Used in the synthesis of styrylquinazolinones which are potential anticancer agents.

Uses

2-Amino-5-fluorobenzoic acid is used for the counterselection of TRP1, a commonly used genetic marker in the yeast Saccharoyces Cerevisiae. An antimetabolite for the tryptophan pathway in yeast, and is toxic by virtue of its antimetabolite conversion to 5-Fluorotryptophan. It can be used for the selection of tryptophan auxotroophs.

Definition

ChEBI: An aminobenzoic acid that is anthranilic acid in which the hydrogen at position 5 on the phenyl ring is replaced by fluorine.

reaction suitability

reaction type: solution phase peptide synthesis

Synthesis

5-Fluoro-2-nitrobenzoic acid

320-98-9

2-Amino-5-fluorobenzoic acid

446-08-2

General procedure for the synthesis of 2-amino-5-fluorobenzoic acid from 2-nitro-5-fluorobenzoic acid: 2-nitro-5-fluorobenzoic acid (10 g, 54 mmol) was dissolved in ethanol (100 mL) and 10% Pd/C catalyst (0.5 g) was added. The reaction was stirred at room temperature for 4 h under hydrogen atmosphere. Upon completion of the reaction, the catalyst was removed by diatomaceous earth filtration. The filtrate was concentrated under reduced pressure to give 8.2 g (98% yield) of the white solid product 2-amino-5-fluorobenzoic acid. Product melting point: 142 °C. 1H NMR (DMSO-d6) δ: 6.71 (dd, J = 4.9, 8.9 Hz, 1H), 7.15 (dt, J = 2.9, 8.4 Hz, 1H), 7.37 (dd, J = 2.9, 9.8 Hz, 1H), 8.60 (s, 1H).EIMS m/z 156 (M + 1).
