Versuchsvorschrift

A mixture of 1.1 g. of p-n-butyl benzoic acid, 2.5 g. of thionylchloride, 5 ml. of toluene and a small amount of zeolite was refluxed for about 4 hours to react them. After the reaction, excess of thionylchloride, dissolved hydrogen-chloride gas, sulfur dioxide gas, and toluene were vaporized to remove them by a rotary evaporator. A crude p-n-butyl benzoylchloride was obtained as a residue. On the other hand, 1.1 g. of 2,3-dichloroaniline was dissolved in 10 ml. of acetone and 1.3 g. of potassium carbonate was gradually added with stirring to suspend it.
