Versuchsvorschrift

To a 100 mL round-bottomed flask equipped with a magnetic stirrer bar and an addition funnel was added 4-hydroxybenzophenone (1 g, 5.04 mmol) and CH2Cl2 (35 mL). The mixture was cooled to 0° C. and methacryloyl chloride (0.39 mL, 4.04 mmol) was added in one portion. After 30 minutes, triethylamine (0.7 mL, 5.04 mmol) dissolved in CH2Cl2 (10 mL) was added dropwise over 30 minutes. The reaction mixture was allowed to stir for a further 1 hour at 0° C. and then at room temperature for 3 hours. After this time, the organic mixture was washed with 0.1% NaOH (3×100 mL) and water (5×100 mL). The combined organic layers were dried over MgSO4 and then concentrated in vacuo to afford a crude product. The crude product was purified by column chromatography (100% CH2Cl2) to provide the compound as a white solid (yield=75%, 1 g).
