A 4-methoxy-2-methyl-benzyl cyanide synthesis method

-

, (2019/02/02)

The invention relates to a synthesis method for 4-methoxy-2-methyl benzyl cyanide. The synthesis method takes 3, 4-dimethylphenol which is cheap and simple and easy to purchase as the raw material, and comprises six steps: methylation, oxidation, Witting reaction, alkene ether hydrolysis, oximation and dehydration. The synthesis method uses the simple and cheap raw material, is simple to operate, is easy for industrial production, has short production cycle, only needs purification in the last step of the six so as to obtain high-quality 4-methoxy-2-methyl benzyl cyanide, and avoids using extremely toxic substances like NaCN and KCN, thus filling the blank home and abroad.
