该中间体在本合成路线中的序号：(VII)

The sulfanylpyrrolidine (V) can be obtained as follows: Esterification of 3-nitrobenzoic acid (VII) with allyl bromide and K2CO3 in DMF gives the corresponding allyl ester (VIII), which is reduced with SnCl2 in refluxing ethyl acetate to yield the 3-aminobenzoate (IX). The condensation of (IX) with the pyrrolidinecarbonyl chloride (X), obtained from the corresponding carboxylic acid (XI) and oxalyl chloride, by means of NMM in dichloro-methane affords the expected amide (XII), which is finally deacetylated with NaOH in allyl alcohol.
