Lithium diisopropylamide is a strong, nonnucleophilic base. It is often freshly prepared by treating a certain reactant with n-butyllithium (n-BuLi). Draw the starting material and draw the product (lithium diisopropylamide). Include any charges, but you do not need to draw electron pairs.
By reacting Diisopropylamine with n-Butyllithium in dry cold conditions with Tetrahydrofuran as solvent, Lithium diisopropylamide is prepared. Please see the attached image for reference.
