Versuchsvorschrift
In anhydrous tetrahydrofuran, 680 mg of 2,4-dichloropyrimidine was substituted with 680 mg of imidazole. The reaction mixture was then treated according to the procedure of Example 5 to yield 840 mg of the 2-chloro-4-(1-imidazolyl)pyrimidine, recrystallized from a mixture of n-hexane and ethyl acetate, having a melting point of 127.5°-128° C.
