실험 절차

A stirred solution of 13.0 grams (0.042 mole) of 2-nitro-5-(naphth-2-ylthio)benzonitrile in 200 mL of 2-methoxyethyl ether was cooled to 0° C., and a solution of 30.3 grams (0.134 mole) of stannous chloride dihydrate in 91 mL of concentrated hydrochloric acid was added. Upon completion of addition, the reaction mixture was allowed to warm to ambient temperature, where it was stirred during a 2 hour period. After this time, the reaction mixture was poured, with stirring, into a mixture of 260 grams of aqueous 50% potassium hydroxide in 300 grams of ice. An oily material, which dropped out of the solution, ultimately solidified. The solid was collected by filtration and was washed with water. The solid was dissolved in methylene chloride and was dried with magnesium sulfate. The mixture was filtered, and the filtrate was concentrated under reduced pressure, yielding 12.0 grams of 2-amino-5-(naphth-2-ylthio)benzonitrile. The NMR spectrum was consistent with the proposed structure.
