Reaction Steps

2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Pentadecafluoro-octanoyl chloride (0.30 g, 0.7 mmol) was added to a solution of 6-[4′-(hydroxy)biphen-4-yl]-3-phenyl-3-(4-pyrrolidinophenyl)-3H-naphtho[2,1-b]pyran (0.40 g, 0.7 mmol) in DCM (30 mL) containing pyridine (2 mL) under N2 at 0° C. with stirring. The mixture was stirred at room temperature for 1 h, poured into HCl (2 M, 100 mL), extracted with DCM (3×50 mL), washed with water (100 mL), dried (MgSO4) and the solvent removed under reduced pressure. The residue was filtered through a short plug of silica using DCM (60% in hexanes) as eluent and the solvent removed under reduced pressure. The residue was dissolved in Et2O, hexane was added and the solvent reduced. The resulting precipitate was filtered to give the title compound (0.17 g, 25%) as a colourless powder, mp 144-145° C.
