80 °C

A suspension of 0.4 g (0.93 mmol) of 9-(4-bromo-butyl)-9H-fluorene-9-carboxylic acid-(2,2,2-trifluoroethyl)-amide, 0.153 ml (1 mmol) of 1-phenylpiperazine, 0.8 g of potassium carbonate and 1 ml water in 30 ml dimethylformamide is stirred for 10 hours at 80° C. The reaction mixture is then poured onto water, extracted with ethyl acetate and the organic phase is dried over sodium sulphate. Purification is by column chromatography on silica gel (eluant: dichloromethane/methanol=15:1).
