実験手順

Following the procedure described in Example 42(h), 0.40 g of t-butyl α-[6-amino-2-(2-furyl)-5-oxoperhydro-1,4-thiazepin-4-yl]acetate [prepared as described in step (f) above] was N-alkylated using 0.68 g of ethyl 2-bromo-4-phenylbutyrate. The resulting product was subjected to silica gel column chromatography eluted with a 1:20 by volume mixture of ethyl acetate and methylene chloride, to separate it into two isomers, A and B, (ascribed to the asymmetric carbon atom to which the phenethyl group is attached).

後処理

  1. washeluted with a 1:20 by volume mixture of ethyl acetate and methylene chloride
  2. customto separate it into two isomers
