Participants

Reaction Steps

To a solution 11-chloro-5-methylbenzofuro[3,2b]quinoline trifluoromethanesulfonate from Example 56 (65 mg, 0.156 mmol) in 2-ethoxyethanol (5 ml) was added 4-chlorothiophenol (23 mg, 0.156 mmol) causing the reaction mixture to became a bright yellow. After 5-7 min, TLC showed the disappearance of the starting material. The reaction mixture was cooled to room temperature, diluted with hexane (100 mL), cooled below room temperature, filtered and dried to afford 50 mg (63%) of the title compound, mp 150-151° C.; 1H NMR (CDCl3) δ8.71 (d, 1H, J=7.6), 8.60 (s, 2H), 8.23 (s, 1H), 7.96 (s, 1H), 7.86 (t, 1H, J=6.8), 7.64 (m, 2H), 7.44-7.37 (m, 4H), 5.06 (s, 3H); 13C NMR (CDCl3) δ 159.65, 146.54, 140.91, 139.53, 137.16, 136.95, 136.13, 135.33, 25 135.10, 130.24, 129.26, 127.46, 126.74, 126.65, 126,48, 126.08, 119.23, 116.29, 113.54, 41.25; MS (FAB, m/z) 376 (M+).
