Devise a synthesis of the tripeptide sequence Phe Thr Lys using acid chloride below and N-methylmorpholine (NMM) for your coupling. Propose a detailed reaction mechanism for this step. You may use any readily available reagents/ protecting groups for your synthesis. In your answer you should clearly state the chosen reagents and how they are introduced and removed in your synthesis. Mechanistic details, for these steps are NOT required.
