Following is a retrosynthetic analysis for the anthelmintic (against worms) diethylcarbamazine. N. `NET2 N. OEt Me Me Diethylcarbamazine (A) (2) OH MENH, CI OEt Me OH Me Methylamine Ethylene (C) (В) Ethyl oxide chloroformate Diethylcarbamazine is used chiefly against nematodes, small cylindrical or slender threadlike worms such as the common roundworm, which are parasitic in animals and plants. Given this retrosynthetic analysis, propose a synthesis of diethylcarbamazine from the three named starting materials.

Question 5

A triester that contains three identical R groups can be extracted from coconut oil. This triester can react with potassium hydroxide in a reaction known as hydrolysis, as shown in figure 5. RCOO RCOO RCOO CH₂ | CH CH₂ Tri-ester + 3 KOH Deduce the value of 'n' in CH3(CH₂)n 3 RCOOK + Figure 5: Reaction showing the hydrolysis of a triester. Product X Using mass spectrometry analysis, it was determined that the coconut triester has a relative molecular mass, Mr= 638.0. In the reaction shown in figure 5, R represents a hydrocarbon chain group that can be written as CH3(CH₂)n.
