QUESTION: Show the mechanism of the reduction of 3-dimethylaminopropiophenone hydrochloride to form the alcohol? PROCEDURE: Add 2.00 g of 3-dimethylaminopropiophenone hydrochloride, 10 mL of distilled water and a magnetic stir bar to a 100 mL beaker, and stir to dissolve. This is the reaction beaker. Add (with stirring) sufficient 10% NaOH (about 5–6 mL) to bring the solution to pH >10. The free base will form and come out of solution as a milky oil. With continued stirring, add enough...
