Beckmann Rearrangement:

http://en.wikipedia.org/wiki/Beckmann_rearrangement

I think it is a great thought on the loss of the proton from the nitrogen in the transition state.  I would greatly appreciate some thoughts on this matter.

Below is my target molecule and I think my proposed route is easier and would give good yields.  Been reading some older papers and the chemistry is sound.  What do you guys think?

Cheers,

Have a good weekend!

In my haste in drawing the scheme, I forgot about the middle step of making a acid chloride.  I apologize.

Nothing wrong with that, you can form amides by dehydration of ammonium salts, you just need rather a lot of heat.

I have made formamides from formate salts of primary amines.
