Procedure

2-Anilino-4-chloro-6-(1-propynyl)pyrimidine (1.7 g) prepared in Example 2, 1.9 g of 54% aqueous solution of dimethylamine and 0.7 g of KOH were added to 20 ml of THF and the mixture was stirred at room temperature for 24 hours. The reaction liquid was poured in water and extracted with benzene. Then, the benzen layer was dried over Glauber's salt and concentrated, the residue was recrystallized from n-hexane-ethanol to afford 1.5 g of 2-anilino-4-dimethylamino-6-(1-propynyl)pyrimidine (yield: 85%). Melting point: 150°-152° C.
