Heat the reaction mixture to 85° C., and stir for 12 hours. Pour the resulting mixture into water, and extract with EtOAc (2×100 mL). Dry the combined organics over sodium sulfate; filter; collect the filtrate; and concentrate the filtrate under reduced pressure. Purify the residue by silica gel chromatography eluting with 50:1 petroleum ether:EtOAc to give the title compound (320 mg, 66.5% yield) as a white solid. 1H NMR (300 MHz, CDCl3,) δ 8.09 (s, 1H), 7.90 (s, 2H), 3.80 (s, 3H).
