合成路线1
该中间体在本合成路线中的序号:(IV)Alkylation of p-hydroxybenzaldehyde (I) with 1-(2-chloroethyl)piperidine (II) afforded 4-(2-piperidinylethoxy)benzaldehyde (III). Aldehyde function reduction using NaBH4 provided the benzylic alcohol (IV). Alternatively, alcohol (IV) can be obtained by reaction of 4-hydroxybenzyl alcohol (A) with 1-(2-chloroethyl)piperidine hydrochloride (II) by means of NaOH and benzyl triethylammonium bromide in toluene.The hydrochloride salt of (IV) was then treated with SOCl2 to furnish chloride (V).

合成路线2
该中间体在本合成路线中的序号:(IV)Alkylation of 4-hydroxybenzaldehyde (I) with 1-(2-chloroethyl)piperidine hydrochloride (II) in the presence of K2CO3 yielded (piperidinylethoxy)benzaldehyde (III), which was further reduced to the benzylic alcohol (IV) with methanolic NaBH4. Coupling of (IV) with thioacetic acid according to the Mitsunobu procedure yielded thioacetate ester (V), which was converted to the corresponding thiol (VI) by reductive cleavage of the thioester group with LiAlH4.
