合成路线1
该中间体在本合成路线中的序号：(XIX)The condensation of 3,4-dimethylpyridine (XV) with 4-(p-fluorophenyl)-4,4-ethylenedioxy-1-chlorobutane (XVI) gives the corresponding pyridinium salt (XVII), which by reaction with p-methoxybenzylmagnesium chloride (I) in ether yields the dihydropyridine (XVIII). The reduction of (XVIII) with NaBH4 in methanol affords the tetrahydropyridine (XIX), which is finally cyclized by refluxing with AlBr3 in CS2; this reaction can also be performed by heating (XIX) with 48% aqueous HBr at 130 C.
