N-(2-Butynyloxy)phthalimide (III) was obtained by the Mitsunobu coupling between 2-butyn-1-ol (II) and N-hydroxyphthalimide (I). Subsequent hydrazinolysis of (III) gave the O-alkynyl hydroxylamine (IV). This was finally condensed with quinuclidin-3-one (V) in methanol to furnish the corresponding oxime.
