Procedure
Following the procedure described in Example 42(h), 0.30 g of t-butyl α-[6-amino-2-(2-furyl)-5-oxoperhydro-1,4-thiazepin-4-yl]acetate [obtained as described in Example 56(f)] was N-alkylated using 0.50 g of butyl 2-bromo-4-phenylbutyrate. The resulting product was subjected to silica gel column chromatography using a 1:40 by volume mixture of ethyl acetate and methylene chloride as eluent, to isolate two isomers, A and B, (ascribed to the asymmetric carbon atom, to which the phenethyl group is attached).
