You can synthesize pyridine-2,6-dicarbonyl dichloride with the Hantzsch pyridine synthesis.

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

Hydrolysis of the ester and conversion to the acyl chloride yields your product.

you should do your own research

oops my bad... you can oxidize 2,6-lutidine (commercially available) using potassium permanganate.

Just out of curiosity, why is this compound of such interest to you?  If you are not a student, and you don't seem to someone in the professional fields related, so...

But really, what is special about this compound that you so desperately need to know?
