실험 절차

4-Methoxycinnamonitrile was hydrogenated in ethanol with palladium hydroxide on carbon to give 3-(4-methoxyphenyl)-propionitrile. A mixture of anhydrous cerium (III) chloride (1.99 g, 8.1 mmol) in dry THF (12 mL) was stirred for 3 hours at room temperature, cooled to −78° C., and treated with MeLi (5.8 mL, 8.1 mmol). After stirring for 1 hour at −78° C. the reaction mixture was treated with 3-(4-methoxyphenyl)propionitrile (0.45 g, 2.8 mmol). The reaction mixture was stirred for 5 hours at −78° C. and then quenched with ammonium hydroxide. After warming to room temperature, the mixture was filtered, and the filtrate diluted with water and extracted with diethyl ether. The diethyl ether layer was dried over sodium sulfate and evaporated. The crude oil was purified by normal-phase chromatography to give 150 mg of 1,1-dimethyl-2-(4-methoxyphenyl)ethylamine as a light yellow oil.
