pay attention it is insoluble amine

Answer 1

Answer:

The answer depends on the entire molecule. Imine is only one part of the molecule.

TLC plates are a good guide to purification. A variety of solvents could be run, you want the Rf to be between 0.2 and 0.5. You may need a modifier such as TEA. I'd start with hexane/ethyl acetate and dichloromethane/methanol solvent systems.

If you think the answer is correct...plzzzz give a thanks......:-)
