最后，用3-甲酰-4-羰基口恶唑烷-5-酮乙酸与L-苯丙氨酸甲酯盐酸盐在溶剂中进行接肽反应，然后在甲醇/盐酸混合体系中进行脱甲酰保护基，从而得到最终目标产物，产率为89.2%。

Both the and DtV$ for the glycyl dipeptides increase with increasing molality of sodium acetate. The interactions between charged center or glycyl units of the peptide and ions dominate those between alkyl groups of the peptide and the ions. The interaction between the peptides and sodium acetate is mainly pairwise. The results were interpreted successfully by the cosphere overlap model.
