m-Toluidine synthesis

12synthesis methods
m-Toluidine can be obtained by hydrocracking of 2,3-dimethylaniline in the presence of an alkaline nickel-magnesium catalyst.[1]
-

Yield:108-44-1 90%

Reaction Conditions:

with ammonium hydroxide;caesium carbonate in acetonitrile for 7 h;Reflux;Green chemistry;

Steps:

3. 2. General Procedure
General procedure: A mixture of the aryl halide (1 mmol), NH4OH (2 mmol), Cs2CO3 (1 mmol) and P4PVy-CuI (0.1 g) in CH3CN (10 mL) was stirred at reflux temperature. After reaction completion (moitored by TLC), the catalyst was recovered by filtration and solvent was evaporated. The residue was poured into a saturated NaCl solution, extracted with ethyl acetate and dried over anhydrous MgSO4. Evaporation of the solvent was followed by column chromatography on silica gel afforded the pure products.
