Reaction Steps

5.7 G. of 4-chloro-5-cyano-2-(4-n-hexylphenyl)-pyrimidine are reacted in 250 ml. of 50% dioxane with 21.9 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-hexylphenyl)-pyrimidine as colorless crystals having a melting point of 86.3°-87.8° C. (smectic); nematic at 101.3° C; clearing point 102.6°-103.2° C. The substance is identical with the compound obtained according to Example 10.
