In 6 ml of N,N-dimethylformamide were dissolved 150 mg of 4-chloro-6-(2,3-difluorophenyl)pyrimidine and 56 mg of 3-butyn-2-ol, to which 32 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 12 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 120 mg of 4-(2,3-difluorophenyl)-6-(1-methyl-2-propynyloxy)pyrimidine (the present compound (134)).
