Procedure
In 2 ml of tetrahydrofuran was suspended 0.03 g of sodium hydride (60% in oil), to which 0.3 ml of a solution containing 0.26 g of 4-chloro-6-(2-hydroxy-1,2-dimethylpropyloxy)pyrimidine was added dropwise at room temperature, followed by stirring for 10 minutes. To this was added dropwise 0.3 ml of a solution containing 0.11 g of iodomethane in tetrahydrofuran, followed by further stirring at the same temperature for 4 hours. To this was added dropwise 0.3 ml of a solution containing 0.06 g of 2-butyn-1-ol in tetrahydrofuran at room temperature and further added 0.03 g of sodium hydride (60% in oil), followed by stirring for 5 hours. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution, which was extracted three times with t-butyl methyl ether. The combined organic layers were washed with a saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate, and then concentrated. The residue was subjected to silica gel column chromatography to give 0.04 g of 4-(2-butynyloxy)-6-(2-methoxy-1,2-dimethylpropyloxy)pyrimidine (the present compound (31)).
