Reaction Steps
A mixture of the product from Step C (8 g), copper dust (2 g) and quinoline (40 mL) was heated under reflux for two hours. The hot reaction mixture was poured onto crushed ice (200 g), acidified with 6N hydrochloric acid and filtered. The filtrate was washed with saturated sodium chloride solution, dried (Na2SO4) and filtered and the solvent was evaporated in vacuo, leaving 5 g of waxy solid.
