Sodium hydride → HCID 178461405、化合物

関与物質

反応手順

In 4 ml of tetrahydrofuran was suspended 0.1 g of sodium hydride (60% in oil), to which 0.5 ml of a tetrahydrofuran solution containing 0.23 g of trans-4-methylcyclohexanol was slowly added dropwise with stirring at room temperature. The mixture was stirred at room temperature for 10 minutes and then cooled to 0° C., to which 1 ml of a tetrahydrofuran solution containing 0.3 g of 4,6-dichloropyrimidine was slowly added dropwise, followed by further stirring at room temperature for 4 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 brine, dried over anhydrous magnesium sulfate, and then concentrated. The residue was subjected to silica gel column chromatography to give 0.37 g of 4-chloro-6-(trans-4-methylcyclohexyloxy)pyrimidine.
