After refluxing overnight, the solution was dark brown. Addition of water yielded an orange-brown solution with suspended solid. Solution was filtered and taken to dryness. The residue was treated with 100 mL of pentane stirred overnight and filtered yielding 10.98 g (83%) of beige material. 1H NMR (400 MHz, CDCl3): 7.82 (d, 2H), 7.26 (d, 2H), 7.15 (d, 1H), 7.05 (d, 1H), 6.98 (t, 1 H), 4.56 (s, 2H), 3.09 (septet, 1H), 2.42 (s, 3H), 2.15 (s, 3H), 1.21 (d, 3H), 1.16 (d, 3H).
