How is 4-Methyl-1,3-benzenediol (CAS: 496-73-1) typically synthesized?

4-Methyl-1,3-benzenediol (CAS: 496-73-1) can be synthesized through a classic reduction of the corresponding benzenedicarboxylic acid using sodium borohydride. The reaction is carried out in an aqueous medium, and the use of a high-purity reducing agent is crucial for obtaining high yield and selectivity. The process is typically conducted under gentle conditions to maintain the structural integrity of the product.
