Procedure
Crude p-nitrobenzyl 2-bromomethyl-3-(tert-butyldimethylsilyloxy)-5-methoxy-6-methylbenzoate, as obtained in Example 23 (d), was reacted with N-[N-(tert-butoxycarbonyl)-D-seryl]-L-cysteine methyl ester in an analogous manner to the procedure described in Example 1 (f), and the product was subjected in an analogous manner to the sequence of procedures used in Example 23 to yield tert-butyl (4R, 7R)-1,3,4,5,6,7,8,10-octa-hydro-14-hydroxy-12-methoxy-4-methoxycarbonyl-11-methyl-6,10-dioxo-9,2,5-benzoxathiaazacyclododecine-7-carbamate as a white solid.
