Better use some allyl chloride to promote allynation, this chloride u can seperate after reaction completion, and use always aprotic solvents for imidazoline.

Laurent F Bornaghi

This compound is cheap as chips, why not buying it: Acros - 25g less than $50!

Now chemistry: Try NaHCO3 in methanol at RT, should do it.

Good luck
