What is Methyl 4-aminobenzoate?
Chemical properties
white to beige crystals or crystalline powder
The Uses of Methyl 4-aminobenzoate
Methyl 4-aminobenzoate is used in the synthesis of guanidine alkaloids, (±)-martinelline and (±)-martinellic acid by a protic acid catalyzed hetero Diels-Alder coupling reaction with N-Cbz 2-pyrroline. It is also used in organic synthesis and acts as a dye intermediate. Further, it is used to prepare 4-(2-methyl-4-oxo-4H-quinazolin-3-yl)-benzoic acid methyl ester by reacting with 2-acetylamino-benzoic acid.
