Participants

Reaction Steps

To a slurry of 10.0 g. of 2-(1H-imidazol-1-yl)-1-(9H-fluoren-2-yl)ethanone in 100 ml. of toluene were added 4.53 g. of ethylene glycol and 13.9 g. of p-toluenesulfonic acid. The mixture was heated overnight at reflux with the azeotropic removal of water. The reaction was poured into water and the resulting solid was removed by filtration. The solid was basified with 50 percent sodium hydroxide and extracted with ethyl acetate. The ethyl acetate was washed with water, followed by a saturated sodium chloride solution, dried over sodium sulfate, filtered, and evaporated in vacuo. The residue was crystallized from acetone to provide 8.64 g. of the title product, m.p. 163°-166° C.
