Procedure

In 10 ml of N,N-dimethylformamide were dissolved 457 mg of 4-chloro-6-(2-fluorophenyl)pyrimidine and 277 mg of 3-pentyn-1-ol, to which 132 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 467 mg of 4-(2-fluorophenyl)-6-(3-pentynyloxy)pyrimidine (the present compound (153)).
