Procedure

5.0 G. of 4-chloro-5-cyano-2-(4-ethoxyphenyl)-pyrimidine are reacted in 250 ml. of 50% dioxane with 22.2 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-ethoxyphenyl)-pyrimidine as colorless crystals having a melting point of 152.6°-153.0° C. which on cooling are nematic (monotropic) at 149.7° C.
