该中间体在本合成路线中的序号：(V)Reaction of 3,5-dibromopyridine (I) with sodium ethoxide gave 3-bromo-5-ethoxypyridine (II). Palladium-catalyzed coupling of bromopyridine (II) with 3-buten-1-ol (III) yielded the pyridinylbutenol (IV), which was further converted to tosylate (V). Displacement of the tosylate group of (V) with methylamine then gave amine (VI).
