Procedure

To a mixture of THF (20 mL) and dimethylamine (20 mL, 40% wt in water) at 0° C. was added 2,4,6-trimethylbenzyl chloride (5 g, 29.64 mmol). The mixture was allowed to warm up to room temperature and stirred for 4 h before THF was evaporated and the aqueous residue was extracted with ether. The organic layer was worked up and concentrated as usual to give 2,4,6-trimethylphenyl-dimethylamine in quantitative yleld. This compound was then nitrated and the resulted nitro compound reduced to the corresponding aniline as demonstrated in Example 14.
