Condensation of (phosphoryloxy)carbapenem (XVI) with 3-mercapto-1-(1,3-thiazolin-2-yl)azetidine (XI) gave thioether (XVII). The p-nitrobenzyl ester group of (XVII) was then deprotected with Zn powder to afford carboxylic acid. Finally, treatment of (XVIII) with either iodo or chloromethyl pivalate (XIX) produced the target compound.
