Uses
5-Amino-2-methylbenzoic Acid is used as a reagent in synthesis of several organic compounds including that of dihydroxylphenyl amides which are Hsp90 inhibitors. Also used in synthesis of a series of 2,5-diaminopyrimidine inhibitors of bruton’s tyrosine kinase with potential for use in cancer drug development.

General procedure for the synthesis of 5-amino-2-methylbenzoic acid from 2-methyl-5-nitrobenzoic acid: 2-methyl-5-nitrobenzoic acid (30.0 g, 0.166 mol) and Pd/C catalyst (1.8 g) were suspended in anhydrous methanol (1600 mL). The reaction mixture was stirred at 40 °C for 3 to 4 h at a hydrogen pressure of 50 Psi. The progress of the reaction was monitored by thin layer chromatography (TLC, unfolding agent ratio of petroleum ether: ethyl acetate = 1:2) and after confirming that the reaction was complete, the catalyst was removed by filtration. The filtrate was concentrated under reduced pressure to afford 5-amino-2-methylbenzoic acid (24 g, 96% yield) as a white solid.1H NMR (400 MHz, CDCl3) data were as follows: δ 7.10 (s, 1H), 6.89-6.91 (d, J=8.0 Hz, 1H), 6.64-6.66 (dd, J=8.0 Hz, 1H), 2.31 (s, 3H).
