Acetic Acid → Cyclohexanecarbonitrile, 1-(1-naphthalenyl)-4-oxo-

Participants

Reaction Steps

A mixture of 16.73 g. (0.055 mole) of methyl 5-cyano-5-(1-naphthyl)-2-oxocyclohexanecarboxylate (prepared in Example 11) in 400 ml. of acetic acid and 200 ml. of 10% sulfuric acid is stirred mechanically for about 44 hours. The mixture is then allowed to cool and diluted with water. This mixture is extracted thoroughly with benzene. The organic layer is successively washed with water, sodium bicarbonate solution and brine and evaporated to dryness. The solid residue is recrystallized from acetone to give 10.3 g. (76% yield) of 4-cyano-4-(1-naphthyl)cyclohexanone, having a melting point of 213° to 215°C.
