Step-by-step solution

The given reaction involves a secondary amine reacting with a ketone (acetone) in the presence of an acid catalyst ( H^+ ). When a secondary amine reacts with a ketone under acidic conditions, it undergoes nucleophilic addition followed by dehydration to form an enamine. The steps are as follows: 1. The lone pair on the nitrogen atom of the secondary amine attacks the protonated carbonyl carbon of acetone, forming a hemiaminal intermediate. 2. Protonation of the hydroxyl group and subsequent loss of a water molecul
