Following a procedure similar to that described in Example 21(b), but using 4-nitrobenzyl (1R,5S,6S)-2-(2-diethylcarbamoylphenylsulfinyl)-1-methyl-6-[1(R)-t-butyldimethylsilyloxyethyl]-1-carbapen-2-em-3-carboxylate (prepared as described in Example 39) and thiophenol as starting materials, in relative proportions similar to those used in that Example, the title compound was obtained as crystals in a yield of 72%. Recrystallization of this product from a mixture of ethyl acetate and hexane afforded crystals of the title compound melting at 149° to 150° C.
