SUMMARY

Lab production of 2,6-Xylidine is challenging due to difficulties in the production or reduction of 1,6-dimethyl nitrobenzene, which requires over 50 atmospheres of pressure in industrial settings. An alternative approach involves starting with nitromesitylene, focusing on two strategies: removing the para methyl group and reducing the nitro group to an amine, or reversing these steps. Key challenges include selectively demethylating nitromesitylene and effectively reducing it to an amine, with the presence of additional methyl groups complicating the reduction process.

PREREQUISITES
  • Understanding of nitro group reduction techniques
  • Familiarity with methyl group demethylation methods
  • Knowledge of organic synthesis principles
  • Experience with high-pressure chemical reactions
NEXT STEPS
  • Research selective demethylation techniques for nitromesitylene
  • Study reduction methods for nitro groups to amines
  • Explore high-pressure synthesis methods in organic chemistry
  • Investigate alternative synthetic routes for 2,6-Xylidine
USEFUL FOR

Chemists, organic synthesis researchers, and students interested in the production of pharmaceutical precursors like 2,6-Xylidine.

Lab production of 2,6-Xylidine appears to be difficult. Apparently either the production or reduction of 1,6-dimethyl nitrobenzene is "hard". Industrial production involves 50+ atmospheres of pressure, which falls far outside of my definition of "lab production".

I'm interested in taking a third approach: start with nitromesitylene.

Strategy 1: Somehow, magically, remove the methyl group that is para to the nitro group, then reduce the nitro group to an amine.
Strategy 2: Reverse the steps above: Reduce, then demethylate the aminomesitylene

My questions for all you "real" chemists out there:
  1. How do I remove the correct methyl group from nitromesitylene?
  2. What challenges do I face in reducing it to an amine? Reducing 4-nitrotoluene acid to 4-aminotoluene isn't too difficult, I hear. I assume the additional methyl groups are the cause of any difficulty?
Thank you in advance - Any help or pointers gratefully accepted
