2,2-Dimethoxypropane → HCID 57682793, compound

Participants

Reaction Steps

390 mg of 3-(4-(t-butyldimethylsilyloxy-methyl)-2-methoxy-5-nitrophenyl)propane-1,2-diol was dissolved in 8 ml of acetone. Then, 0.33 g of dimethoxypropane and 26 mg of pyridinium p-toluenesulfonate were added to the reaction solution. The obtained mixture was then stirred at room temperature for 41 hours. Thereafter, the reaction solution was concentrated under a reduced pressure. The residue was diluted with ethyl acetate and then washed with water and a saturated sodium chloride aqueous solution. The organic layer was dried over magnesium sulfate and then concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate), so as to obtain 358 mg of the subject compound.
