Water → 4-(2,3-Difluorophenyl)-6-(1-methyl-2-butynyloxy)pyrimidine

Participants

Reaction Steps

In 5 ml of N,N-dimethylformamide were dissolved 135 mg of 4-chloro-6-(2,3-difluorophenyl)pyrimidine and 60 mg of 3-pentyn-2-ol, to which 29 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 5 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 130 mg of 4-(2,3-difluorophenyl)-6-(1-methyl-2-butynyloxy)pyrimidine (the present compound (167)).
