実験手順

In anhydrous tetrahydrofuran, 159 mg of 2-chloro-4-methoxy-6-methylpyrimidine was substituted with 68 mg of pyrazole. The reaction mixture was treated according to the procedure of Example 5 to yield 103 mg of 4-methoxy-6-methyl-2-(1-pyrazolyl)pyrimidine, and recrystallized from n-hexane to give a compound having a melting point of 52.5°-53° C.
