Reaktionsschritte

9-Anthracenemethanol (30 g) was dissolved in freshly distilled THF (150 mL). To the solution triethylamine (30 mL) and pyridine (20 mL) were added and the mixture was cooled down to 0° C. Then methacryloyl chloride (21 mL) was added dropwise. After the addition, ice-water bath was removed and the mixture was stirred for 1 hour. After water (75 mL) was added to the reaction flask, the solution was transferred into separatory funnel and extracted with diethyl ether (500 mL). The extract was washed with aqueous HCl (1 M, 150 mL), aqueous NaHCO3 (5%, 150 mL), and brine (150 mL), respectively. The solvent was evaporated in vacuum and recrystallized with methanol. (Product: 21 g) 1H NMR (500 MHz, CDCl3): δ 8.55 (s, 1H), 8.41 (d, J=8.9 Hz, 2H), 8.07 (d, J=8.4 Hz, 2H), 7.61 (t, J=7.7 Hz, 2H), 7.53 (t, J=7.9 Hz, 2H), 6.25 (s, 2H), 6.08 (s, 1H), 5.54 (s, 1H), 1.95 (s, 3H) ppm.
