Compound (XIX) is condensed with 2-[1-(acetylsulfanylmethyl)cyclopropyl]acetic acid methyl ester (XX) by means of Cs2CO3 in acetonitrile yielding the expected condensation product (XXI). Finally, this compound is treated successively with pyridine and p-toluenesulfonic acid to eliminate the tetrahydropyranyl protecting group, and with NaOH to hydrolyzed the acetate ester group of (XXI). 4) The 2-[1-(acetylsulfanylmethyl)cyclopropyl]acetic acid methyl ester (XX) has been obtained as follows: The reduction of diethyl cyclopropane-1,1-dicarboxylate (XXII) with LiAlH4 in THF gives 1,1-cyclopropanedimethanol (XI), which is monobenzoylated with benzoyl chloride (XXIII) and pyridine in dichloromethane yielding benzoic acid 1-(hydroxymethyl)cyclopropylmethyl ester (XXIV). The mesylation of (XXIV) as usual affords the mesylate (XXV), which is treated with NaCN in DMSO to give 2-[1-(benzoyloxymethyl)cyclopropyl]acetonitrile (XXVI). The hydrolysis of (XXVI) with KOH in refluxing ethanol, followed by methylation with diazomethane, yields methyl 2-[1-(hydroxymethyl)cyclopropyl]acetate (XXVII), which is mesylated as usual affording the mesylate (XXIII). Finally, this compound is treated with cesium thiocetate in dichloromethane to give (XX).

The selective silylation of the diol (VII) with tert-butyldimethylsilyl chloride (TBDMS-Cl)/dimethylaminopyridine (DMAP) and imidazole in dichloromethane gives the monosilylated compound (XVI), which is treated with dihydropyran and triphenylphosphonium bromide to yield (XVII) with the tertiary alcohol protected as its tetrahydropyranyl ether. The desilylation of (XVII) with tetrabutylammonium fluoride (TBAF) in THF affords the secondary alcohol (XVIII), which is mesylated as usual giving the mesylate (XIX).
