Reaction Steps

4-(2,3-dihydroxy-propoxy)-1-fluoro-thioxanthen-9-one (2.9 g, 9 mmol), 3-chloropropionyl chloride (9.5 g, 75 mmol), potassium carbonate (10.4 g, 75 mmol) and 2,6-di-tert-butyl-4-methylphenol (0.1 g, 0.00045 mol) were added to acetonitrile (35 mL). The reaction mixture was heated at 81° C. and stirred for 6 hours. After cooling down to room temperature, dichloromethane (200 mL) was added and the reaction mixture was extracted with distilled water (200 mL). The organic layer was separated, dried over MgSO4 and evaporated under reduced pressure. The product was purified on a Prochrom LC 80 Column using dichloromethane/ethyl acetate (98/2) as eluent and Kromasil Si60A 10 μm as packing material, to yield 1.2 g of acrylic acid 2-acryloyloxy-3-(1-fluoro-9-oxo-9H-thioxanthen-4-yloxy)-propyl ester.
