General Description
3,4-Dihydroxy-5-methoxybenzaldehyde can be obtained by reactting 5-iodovaniliin with sodium hydroxide and copper sulfate solution.
Synthesis
The bromination reaction of vanillal and bromine generate 5-bromovanillal, which is then reacted with sodium hydroxide solution under the participation of copper powder to give 5-Hydroxyvanillin.
