Reaktionsschritte

Following a procedure similar to that described in Example 18, 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 ethylmercaptan as starting materials, in relative proportions similar to those used in that Example, the title compound was obtained as a crystal in a yield of 83%. Recrystallization of this product from diisopropyl ether afforded the title compound in the form of crystals melting at 121°-121.5° C.
