Draw the structures of the organic products in each reaction of thefollowing two-step synthesis. (Hint: Thenucleophilic amine attacks the electrophilic carbonyl carbon, andthe resulting intermediate undergoes a proton shift anddehydration. Recall what is eliminated in a dehydration process.The second step is a reduction reaction; the reducing agent isNaBH3CN (or H2, metal catalyst). The aromatic ring is unaffected bythese reagents. Look at the product of the first reaction andconsider what can be easily reduced.)
