実験手順

Compound 6 (5.0 g, 10.3 mmol) and 6.8 g of 84% polyphorphoric acid were added into a 250 mL 3-neck flask equipped with a condenser. The system was flashed with argon for 15 minutes before 50 mL of anhydrous chlorobenzene was added. The mixture was heated at 140° C. for 40 hours before it was cooled down to room temperature. Dichloromethane (100 mL) was added. The organic mixture was washed with saturated NaHCO3 before the solvent was removed under vacuum. Methanol (100 mL) was added before compound 7 (2.0 g, ˜66% yield) was collected as a white solid by filtration, washed with methanol and dried in vacuo. 1H NMR (CDCl3, 500 MHz): δ 7.97 (d, 2H, J=5.5 Hz), δ 7.62 (d, 2H, J=5.5 Hz), 67.51 (s, 2H), δ 4.18 (s, 6H).
