Versuchsvorschrift

0.34 g of t-butyl α-(6-amino-5-oxo-2-phenylperhydro-1,4-thiazepin-4-yl)acetate [prepared as described in Example 7(g) above] was N-alkylated with 0.45 g of butyl 2-bromo-4-phenylbutyrate in the manner described in Example 1(h). The resulting product was subjected to silica gel column chromatography using a 1:40 by volume mixture of ethyl acetate and methylene chloride as the eluent. As a result, the title compound was separated into isomers A and B (resulting from the asymmetric carbon atom to which the phenethyl group is attached).
