Definition

ChEBI: 2-amino-5-chlorobenzoic acid is a member of the class of chlorobenzoic acids that is benzoic acid in which the ring hydrogens at positions 2 and 5 are replaced by amino and chloro groups, respectively. It is an aminobenzoic acid, a member of monochlorobenzenes and a chlorobenzoic acid.

reaction suitability

reaction type: solution phase peptide synthesis

Synthesis

2516-95-2

635-21-2

General procedure for the synthesis of 2-amino-5-chlorobenzoic acid from 5-chloro-2-nitrobenzoic acid: active Raney nickel (2 g) was added to the reaction flask, followed by the addition of an ethanol solution of 5-chloro-2-nitrobenzoic acid (20 g, 110 mmol). The reaction mixture was stirred at room temperature in a hydrogen atmosphere overnight. Upon completion of the reaction, the reaction solution was filtered through diatomaceous earth and the filtrate was concentrated under reduced pressure to give 16 g of white solid product (96% yield). The product was characterized by 1H NMR (DMSO-d6): δ 6.77 (d, J = 8.9 Hz, 1H), 7.24 (dd, J = 2.9, 8.9 Hz, 1H), 7.62 (d, J = 2.9 Hz, 1H), 8.7 (br, 3H); EIMS: 170 (M-H).
