So you're saying that you have 2-bromo-4,5-dimethoxybenzaldehyde? YES YES YES
and you want 2-bromo-4,5-dimethoxyphenethylamine? no TMA-2

If so, then I would imagine that condensation with MeNO2 with ammonium acetate as catalyst would form a nitrostyrene
Give the description of process
If it's TMA-2 (an amphetamine, rather than just a phenethylamine) you want, then use EtNO2 rather than MeNO2.
Give the description of process please ! (example)
2-Bromo-4,5-dimethoxybenzaldehyde has been prepared, it is reacted with sodium methoxide in methanol, with EtOAc/CuBr as catalyst [4] to form 2,4,5-trimethoxybenzaldehyde
And give the description this of process please ! (example)

Doo you see that littel link at the bottom (both Rhodium and Pikhal) try to clik on one off them.

TMA-2

Stop asking stupid questions.

At least you can ask them at HyperLab first - or yet better read the FAQ there which i specifically wrote for such purposes OR fucking read at least something bee4 asking such profound questions here.

I mean, do you want to practice English or something?
