Procedure

In 10 ml of N,N-dimethylformamide were dissolved 522 mg of 4-chloro-6-(2-fluorophenyl)pyrimidine and 231 mg of 2-pentyn-1-ol, to which 110 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 6 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 470 mg of 4-(2-fluorophenyl)-6-(2-pentynyloxy)pyrimidine (the present compound (86)).
