Reaction Conditions

Reaction Steps

To 2 ml of dimethylsulfoxide were added 183 mg of 4-chloro-6-(2-butynyloxy)pyrimidine, 166 mg of potassium carbonate, and 152 mg of dipropylamine, followed by stirring at 80° C. for 8 hours. The reaction mixture was then left for cooling to room temperature, diluted with ethyl acetate, and washed twice with an aqueous sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel thin layer chromatography to give 179 mg of 4-(2-butynyloxy)-6-(dipropylamino)pyrimidine (the present compound (113)).
