실험 절차

A mixture of 2.28 g (25 mmols) of distilled aniline, 30 mL of acetonitrile, 2.6 mL (31 mmols) of concentrated hydrochloric acid, 30 mL (456 mmols) of distilled acrylonitrile (AN), and 0.36 g (2.5 mmols) of cuprous oxide was stirred for five minutes under nitrogen. A mixture of 2.8 g (31 mmols) of isopropyl nitrite (IPN) and 30 mL of acetonitrile was added dropwise over a period of 20 minutes. The mixture warmed to 45° C. and nitrogen gas evolved. After stirring at ambient temperature for two hours, the dark mixture was worked up to provide an 84% yield of 2-chloro-3-phenylpropionitrile (CPPN).
