The major product obtained in the following reactions is:

(A)(see structure)
(B)(see structure)
(C)(see structure)
✓ Correct
(D)(see structure)

Answer: (C)

Solution

Follow the sequence step by step. The primary amine first undergoes the carbylamine reaction with

CHCl X_{3}

and

KOH

to give an isocyanide. That isocyanide is then reduced under

Pd / C

with

H X_{2}

to the corresponding secondary amine, and finally

KMnO X_{4}

oxidises the benzylic secondary alcohol to a ketone. Collecting these changes, the major product carries the N-substituted amino group and a benzylic ketone at the oxidised position.
