Reaction Steps

5 (4 g) was dissolved in 48% HBr aqueous solution (5 mL) and heated at 65° C. for 2 hrs and then evaporated to dryness. The residue was recrystalized from acetone to yield 2.5 g white crystal, yield 77%. See FIG. 12. 1H NMR: (DMSO) 1.36 (m, 2H), 1.54 (m, 2H), 1.74 (m, 2H), 2.21 (t, 2H), 2.87 (s, 3H), 3.95 (s, 3H), 4.46 (t, 2H), 8.49 (s, 1H), 8.54 (s, 1H). 13C NMR: (DMSO): 10.75, 23.92, 25.14, 28.19, 32.08, 33.37, 45.13, 114.78, 114.82, 128.73, 128.76, 130.04, 130.91, 154.26, 174.20.
