Procedure

To 20 ml of dimethylsulfoxide were added 1.83 g of 4-chloro-6-(2-butynyloxy)pyrimidine, 2.20 g of potassium carbonate, and 20 ml of ethylamine (2.0 M tetrahydrofuran solution), followed by stirring at 50° C. for 8 hours. The reaction mixture was then left for cooling to room temperature, diluted with tert-butyl methyl ether, and washed twice with an aqueous sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and concentrated. The residue was recrystallized from tert-butyl methyl ether to give 1.14 g of 4-(2-butynyloxy)-6-(ethylamino)pyrimidine (the present compound (108)).
