Reaction Steps

A solution of 0.3 g (0.7 mmol) of 9-(4-bromo-butyl)-9H-fluorene-9-carboxylic acid-(2,2,2-trifluoro-ethyl)-amide, 0.2 g (0.98 mmol) of 2-(piperazin-1-yl)-benzoxazole and 1 ml of triethylamine in 10 ml of tetrahydrofuran is refluxed for 48 hours. The reaction mixture is then poured onto water, extracted twice with dichloromethane and the combined organic phases are dried over sodium sulphate. The product is purified by column chromatography on silica gel (eluant: cyclohexane/ethyl acetate=1:1).
