Reaction Steps

To a solution of the Grignard reagent prepared from 2-phenylbromoethane (5.5 g.), magnesium (0.8 g.) and dry ether (60 ml.) is added a solution of 2-methyl-2-(2,5-dimethoxyphenyl)propionitrile (2.75 g.) in dry ether (20 ml.). The ether is distilled off and replaced by dry benzene (50 ml.) and the mixture refluxed for 48 hours. It is then decomposed by careful treatment with dilute sulfuric acid and heated on a steam bath for one hour. The mixture is then extracted with ether, the extract dried (MgSO4) and concentrated to an oil. Distillation of the oil in vacuo affords 2-methyl-2-(2,5-dimethoxyphenyl)-5-phenyl-3-pentanone.
