Reaction Steps
In 10 ml of N,N-dimethylformamide were dissolved 280 mg of 4-chloro-6-(2,3-difluorophenyl)pyrimidine and 96 mg of 2-butyn-1-ol, to which 55 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 8 hours. The reaction mixture was then poured into water and extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated. The resulting residue was subjected to silica gel column chromatography to give 212 mg of 4-(2,3-difluorophenyl)-6-(2-butynyloxy)pyrimidine (the present compound (83)).
