反应详情

In 10 ml of N,N-dimethylformamide were dissolved 449 mg of 4-chloro-6-(2-fluorophenyl)pyrimidine and 272 mg of 3-pentyn-2-ol, to which 130 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 three times with ethyl acetate. The organic layers were combined, 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 510 mg of 4-(2-fluorophenyl)-6-(1-methyl-2-butynyloxy)pyrimidine (the present compound (151)).
