Reaktionsschritte

10-(hydroxymethyl)-9-((methylamino)methyl)anthracene (0.800 g, 3.18 mmol) and K2CO3 (0.56 g, 4.05 mmol) were taken up in 15 mL acetonitrile. A solution of 2,2-dimethylpropane-1,3-diyl(o-(bromomethyl)phenyl)boronate 3 (1.00 g, 3.44 mmol) in 5 mL acetonitrile was added and the mixture was refluxed under nitrogen for 24 h. The mixture was filtered hot on a sintered-glass frit and upon cooling, a yellow solid precipitated. The resulting solid was triturated with acetonitrile/water (4:1, v/v), filtered on a sintered-glass frit and vacuum dried to yield 11 as a bright yellow solid (0.632 g, 51.6% yield): 1H NMR (300.13 MHz, CD3OD) δ 2.58 (s, 3H), 4.58 (s, 2H), 5.22 (s, 2H), 5.61 (s, 2H), 7.62 (m, 6H), 7.80 (m, 2H), 8.18 (m, 2H), 8.58 (m, 2H); 13C—{1H} NMR (75.4 MHz, CD3OD) δ 136.9, 136.2, 135.9, 132.9, 132.7, 131.4, 129.9, 128.3, 127.1, 126.8, 126.5, 124.9, 124.1, 63.8, 57.1, 50.9, 40.7.
