BrS6 was converted to BrS6A by the same methods as Br6A and BrC6A, using butyllithium and dimethylformamide. Products were purified by column chromatography with ethylacetate:hexane (1:30) eluent followed by recrystallization from methanol. Yellow powder is collected at a yield of 50%. For BrS6A, 1H NMR (500 MHz, CDCl3): δ 10.39 (s 1H), 7.64 (s 1H), 7.61 (s 1H), 3.00 (t 2H), 2.91 (t 2H), 1.73-1.65 (m 4H), 1.46 (m, 4H), 1.34-1.28 (m 8H), 0.89 (m 6H).
