Question

Show how you would accomplish the following synthetic transformations. You may use any necessary reagents.$\mathbf{\left(}\mathbf{b}\mathbf{\right)}\mathbf{ethylbenzoate}\to \mathbf{N}\mathbf{-}\mathbf{ethylbenzamide}$

Short answer

Synthetic transformation for ethyl benzoate to N-ethylbenzamide is shown as,

Step-by-step solution

Step-by-Step SolutionStep 1: Use of heating in this reaction

In this reaction heating condition are require for fast reaction and formation of amide product, If we do not provide the heat for this reaction then formation of amide product is very slow and also reaction rate are slow.

Synthesis of N-ethylbenzamide from ethylbenzoate

When ethylbenzoate react with ethyl amine followed by heating then there is a formation of N-ethylbenzamide as a final product, In this reaction ethyl amine acts as a nucleophile and it attack on the carbonyl carbon of ethylbenzoateand there is a formation of N-ethylbenzamide and ethyl alcohol as a by product.

This reaction is favored at a high temperature.
