Acylation of L-proline methyl ester (I) with methoxalyl chloride (II) afforded oxamate (III), which was condensed with 1,1-dimethylpropyl magnesium chloride to produce ketoamide (IV). Hydrolysis of the methyl ester of (IV) with LiOH gave carboxylic acid (V). This was finally coupled with 3,3-diphenylpropyl mercaptan (VI) using DCC and dimethylaminopyridine to give the title thioether.

该中间体在本合成路线中的序号:(X)

3,3-Diphenyl-1-propanol (VII) is converted into the corresponding alkyl bromide (VIII) by treatment with CBr4 and PPh3. Reaction of bromide (VIII) with thiourea provides the isothiouronium salt (IX), which is further hydrolyzed to thiol (X) under alkaline conditions. Finally, acylation of thiol (X) with carboxylic acid (VI) by means of DCC yields the target thioester
