実験手順
2-Nitro-4-thiocyanatoaniline (17.55 g.; prepared as hereinbefore described in Example 6) was added portionwise to a stirred solution of potassium hydroxide (13.4 g.) in ethanol (210 ml.), keeping the temperature below 20° C. After 5 minutes, ethyl iodide (14.4 g.) was added during five minutes. The stirring was continued for a further hour and the mixture was allowed to stand overnight. The mixture was then poured into water (1100 ml.) and extracted with chloroform (3× 300 ml.). The chloroform layers were combined, washed with water (500 ml.), dried over magnesium sulphate, and evaporated to give 1-amino-4-ethylthio-2-nitrobenzene (17.0 g.), in the form of a red oil.
