Step by step solution

01

The given dipeptide

The given dipeptide has two amino acids, - alanine, and serine.

The structure of the required dipeptide is as shown:

02

Protecting amine and carboxylic acid groups

The amine group in alanine is protected by using Boc(tertiary butyloxy carbonyl) reagent. The carboxylic acid group in serine is protected with bezyl alcohol as benzyl ester.

03

Synthesis

The amino acid alanine with a protected amino group, and the amino acid serine with a protected carboxylic acid group will react with each other and form the required dipeptide.
