Procedure

11.23 G. of 4-(4-n-butylpyrimid-2-yl)-benzoic acid amide are maintained at reflux for 90 minutes in a mixture of 250 ml. of ethylene chloride and 4.5 ml. of phosphorus oxychloride with stirring. The mixture, diluted with ether, is washed with 2-N sodium hydroxide and then with water until neutral. The organic phase is dried over sodium sulfate and evaporated to give 11.77 g. of 5-n-butyl-2-(4-cyanophenyl)-pyrimidine which are distilled in a high vacuum; melting point 60.9°-61.8° C.
