beige or light buff to orange | [Uses]
4-Amino-3-methylbenzoic Acid is used in preparation of Amide-substituted Benzo[d]imidazole compounds as selective inhibitors of indoleamine-2,3-dioxygenases. | [reaction suitability]
reaction type: solution phase peptide synthesis | [Synthesis]
At room temperature and under hydrogen atmosphere, 3-methyl-4-nitrobenzoic acid (100 g, 552.04 mmol) was dissolved in methanol (2000 mL) followed by addition of palladium carbon catalyst (5.0 g). The reaction mixture was stirred continuously at room temperature for 24 hours. Upon completion of the reaction, the solid catalyst was removed by filtration. The filtrate was concentrated under reduced pressure to give the light yellow solid product 4-amino-3-methylbenzoic acid (80 g, 96% yield). | [References]
