Reaction Conditions

Reaction Steps

In 4 ml of tetrahydrofuran was suspended 0.11 g of sodium hydride (60% in oil), to which 1 ml of a tetrahydrofuran solution containing 0.25 g of cycloheptanol was slowly added dropwise with stirring at 0° C. The mixture was stirred at 0° C. for 10 minutes, to which 1 ml of a tetrahydrofuran solution containing 0.3 g of 4,6-dichloropyrimidine was added at 0° C., followed by further stirring for 2 hours. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution and extracted three times with t-butyl methyl ether. The organic layers were combined, washed with water, dried over anhydrous magnesium sulfate, and then concentrated. The residue was subjected to silica gel column chromatography to give 0.43 g of 4-chloro-6-cycloheptyloxypyrimidine.
