“…Following combination of the reagents, a clear, pale yellow solution was obtained that was heated (85 °C, 2 h) and stirred. The resulting dark red solution was cooled (0 °C), transferred dropwise over 1h into a vigorously stirred solution of 4,6bis(chloromethyl)dibenzothiophene (1) [35] (1.40 g, 4.98 mmol) in toluene (50 mL, 0 °C), and the combination was then heated (85 °C) and stirred (12 h). The resulting mixture was cooled, diluted with CH 2 Cl 2 (150 mL), and the organic phase washed with brine (2 x 30 mL) and water (3 x 30 mL).…”
