or, o-N,N-dimethyl-aniline, or the dihydrochloride salt, or the sulfate, I don't care.

CAS: N,N-Dimethyl-o-phenylenediamine dihydrochloride, 62654-07-3

2-Amino-N,N-dimethylaniline    2836-03-5
N,N-Dimethyl-o-phenylenediamine    2836-03-5

I will buy you a Snickers bar if you happen to have this chemical in your stockroom and would be willing to send it to me.  This chemical used to be commerically available and I can not find it ANYWHERE anymore.  I would love 2-5 g.  Help?

I checked our inventory and the closest I could come was a para-substituted compound with ethyls instead of methyls. Not sure why we have that. Sorry I can't help.

turns out we can make it!

 

2-bromo-N,N-dimethylaniline (which isn't super expensive) + tBuNH2/Pd/BINAP

100% yield (GC) in 4 hours at 100°C.  SWEET!

that takes our 4 step prep down to 1.

This may be too late, but our stockroom is getting rid of some N,N-dimethyl-o-phenylenediamine dihydrochloride (5g).  I happened across your post looking up what it was for.
