This is a base that is used in a reaction procedure I am trying. It is used in the Michael reaction step of a Robinson annulation.
The paper mentions that diethylamine can be used. Does not say how well it works, however.
If one had chlorotrimethylsilane and diethyl amine; couldnt you just make it?
I would say in a polar aprotic solvent such as ether. Add the nucleophile to the electrophile at 0 degrees.
What do you think?
Google was not much help for the synthesis of diethylamino trimethylsilane

Sure you can make it. You need a base for the HCl.
Try 2,6-lutidine in THF, 2,6-lutidine HCl is almost insoluble in THF.

Of course you do. Would pyridine work?? I dont know if we have lutadine.

Yes pyridine will work.

Just need a scavenger. I should have originally put that. Thank you for reminding me Disco.
I found some 2,6-lutidine actually. I knew I had seen it and sure enough there it was.
I will try the lutidine.
Thanks again!!

Is probably just use two eq of diethylamine in ether and filter off the hydrochloride.
