Question -
1. Provide a mechanism for amide formation between benzoic acid and isopropylamine using DCC.
2. Find another example of a solid-phase reagent that is used in organic synthesis, and give an example of a specific reaction where it has been used. In this case, what advantage does the solid-phase reagent provide over the analogous solution-phase reaction?
