After refluxing overnight, the solution was green-brown. Addition of water yielded a light brown solution with suspended solid. Solution was taken to dryness, resuspended in 75 mL of pentane, filtered, washed with 10 mL of pentane and dried in vacuo yielding 10.56 g (69%) of beige powder. NMR (400 MHz, C6D6): 7.76 (d, 2H), 7.42 (d, 2H), 7.31 (d, 1H), 7.1-6.8 (m, 8 H), 6.78(t, 1H), 4.08 (s, 2H).
