5.2 G. of 4-chloro-5-cyano-2-(4-n-heptylphenyl)-pyrimidine are reacted in 220 ml. of 50% dioxane with 19.3 g. of pre-treated zinc dust and worked up after the reaction in a manner analogous to that described in Example 13. There is obtained 5-cyano-2-(4-n-heptylphenyl)-pyrimidine having a melting point of 96.3° C. (smectic) and clearing point 109.0° C. The substance is identical with the compound obtained according to Example 11.
