Chloroacetaldehyde → 11-Methoxyimidazo[1,2-f]phenanthridine

Participants

Reaction Steps

8-Methoxyphenanthridin-6-amine (0.95 g, 4.24 mmol), 2-chloroacetaldehyde (0.807 mL, 12.71 mmol), and sodium bicarbonate (1.25 g, 14.83 mmol) were added to 43 mL 2-propanol and refluxed for 15 h. After cooling to room temperature, the reaction mixture was filtered thru Celite®. After removal of the solvents, the crude material was triturated with 50 mL hexanes to give 11-methoxyimidazo[1,2-f]phenanthridine (0.99 g, 94%) as an off-white solid. The product was confirmed by GC/MS and NMR.
