Procedure

In 10 ml of N,N-dimethylformamide were dissolved 458 mg of 4-chloro-6-(2-fluorophenyl)pyrimidine and 231 mg of 3-butyn-2-ol, to which 132 mg of sodium hydride (60% in oil) was added, followed by stirring at room temperature for 10 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 506 mg of 4-(2-fluorophenyl)-6-(1-methyl-2-propynyloxy)pyrimidine (the present compound (150)).
