Versuchsvorschrift

1.9 g. of 4-(4-n-heptylpyrimid-2-yl)benzoic acid amide are left for 80 minutes under reflux in a mixture of 40 ml. of ethylene chloride and 0.63 ml. of phosphorus oxychloride, with stirring. The reaction mixture, diluted with ether, is washed with 2N sodium hydroxide solution and then with water until neutral. After evaporation of the organic phase, drying over sodium sulfate, 1.9 g. of 5-n-heptyl-2-(4-cyanophenyl)-pyrimidine result, which are distilled in a high vacuum, having a m.p. of 44.2°-44.7°; cl.p. 50.1°-50.4°.
