Versuchsvorschrift

A mixture of 2,3-dichloro-4-methoxyaniline (19.2 g), n-butylbromide (22.0 g), sodium hydrogen carbonate (40 g) and methylcellosolve (350 ml) is stirred at 95°-100° C. for about 48 hours. The cooled mixture is filtered, and the filtrate is evaporated in vacuo. The remaining material is washed with water and is thereafter recrystallized from ethanol to give the title compound with a melting point of 47°-49° C.
