合成路线图解说明:

Coupling of 3-butyn-1-ol (I) with 4-iodo-1-phenylsulfonylimidazole (II) in the presence of CuI and Pd(PPh3)4 afforded the imidazolylbutynol (III), which was activated as the tosylate (IV) with p-toluenesulfonyl chloride in pyridine. Subsequent displacement of the tosylate group of (IV) by 4-benzylpiperidine (V) using NaHCO3 in hot DMF produced the corresponding N-(imidazolylbutynyl)piperidine with simultaneous cleavage of the benzenesulfonyl protecting group.
