A fluorinated benzoic acid building block

Used as a synthesis intermediate for APIs


2-Fluoro-6-methylbenzoic acid (CAS number 90259-27-1) is an ortho-benzoic acid with both methyl and fluoride substituents sitting at ortho-positions to the carboxylic acid. 2-Fluoro-6-methylbenzoic acid is involved in the synthesis of epidermal growth factor receptor (EGFR) inhibitor with potency of 340 nM. In the synthesis of the EGFR inhibitor, the methyl group of 2-fluoro-6-methylbenzoic acid undergoes radical bromination, enabling nucleophilic substitution to phthalimide. Subsequently, the carboxylic acid group is attached to the allosteric motif through an amination reaction to form the inhibitor.

2-Fluoro-6-methylbenzoic acid is also a key building block of avacopan which is used to treat anti-neutrophil cytoplasmic autoantibody-associated vasculitis.
