Pyridine → HCID 11084789, compound

Participants

Reaction Steps

Glycerol formal (14 g) was dissolved in anhydrous ether (400 ml) and, after adding pyridine (15 g) at −10° C., a solution of chloromethyl chloroformate (25 g) in anhydrous ether (50 ml) was added dropwise over the period of 10 minutes. After the reaction solution was stirred at room temperature for 20 hours, the deposited pyridine hydrochloride was removed by filtration. The filtrate was washed with a saturated sodium chloride aqueous solution (400 ml×2), and then dried over anhydrous magnesium sulfate. The residue obtained by distilling off the solvent under reduced pressure was purified by subjecting it to silica gel chromatography (eluent: ethyl acetate/hexane=1/5→ethyl acetate/hexane=1/3) to obtain chloromethyl (1,3-dioxan-5-yl) carbonate (1.7 g) as a colorless oily product.
