CyHN ch is worth 10 por intermediate #2 from intermediate #1 and for intermediate #3 going to the final product. A. Show the key species in the DCC amine-carboxylic acid coupling. Use proper reaction arrows to form amine OH + N-Cy Intermediate #1 - an adduct from DCC and the carboxylic acid (anhydride-like) - no involvement of he amine yet NHCy -NH₂ (DCC) Cy = cyclohexyl Intermediate #3 - from an internal transfer of protons in #2 that sets up the formation of the amide and the urea byproduct Intermediate #2 - the tetrab intermediate like in any n acyl substitution - add ar and do nothing else

Fill in the three boxes:
2) Another method for the above reaction starts with 4-aminophenol hydrochloride (the conjugate acid of 4-aminophenol). The treatment of this the hydrochloride salt with sodium ethanoate (acetate) buffer produces 4-aminophenol which is then able to react with ethanoic anhydride as per our method. i. Why is 4-aminophenol hydrochloride not suitable for direct reaction with ethanoic anhydride? ii. Draw a mechanism (i.e. curly arrows) showing the deprotonation of 4-aminophenol hydrochloride by sodium ethanoate to form 4-aminophenol (the free base).
