Hydrochloric Acid → 3-(4-Fluorophenyl)-3-methylbutan-2-one

Participants

Reaction Steps

To a solution of 5.84 g 2-(4-fluorophenyl)-2-methylpropionitrile in abs. diethylether are added dropwise at -30° and under inert gas, 22 ml of a 1.6M solution of methyllithium in diethylether. The cooling bath is then taken away and the mixture stirred for 3 hours at room temperature. The reaction mixture is poured onto ice, the organic phase stirred overnight with 6N HCl, washed after separation of the acid phase, dried and evaporated in vacuum. The thus obtained oily residue is reacted further without purification.
