[Application]

1-Methyl-1,2,3-benzotriazole-5-carboxylic acid is an organic intermediate that can be prepared from 4-amino-3-nitrobenzoic acid as a raw material. 4-amino-3-nitrobenzoic acid is then prepared, followed by methylation to obtain methyl 4-methylamino-3-nitrobenzoate, reduction of the nitro group to obtain methyl 4-methylamino-3-aminobenzoate, cyclization to obtain methyl 4-methylamino-3-aminobenzoate, and finally hydrolysis of the methyl ester to obtain 1-methyl-1,2,3-benzotriazole-5-carboxylic acid.
