Chloromethyl Methyl Ether → Methyl 3-hydroxy-5-(methoxymethoxy)benzoate

Participants

Reaction Steps

With ice cooling, to a solution of methyl 3,5-dihydroxybenzoate (14.0 g, 83.3 mmol) and N,N-diisopropylethylamine (11.0 g, 85.0 mmol) in dichloromethane (100 mL) was added dropwise chloromethylmethyl ether (6.84 g, 85.0 mmol), and the mixture was stirred at room temperature for 5 hours. The reaction mixture was diluted with dichloromethane (300 mL), and the organic layer was washed successively with a 3% aqueous hydrochloric acid solution, a saturated aqueous sodium bicarbonate solution and saturated brine, and then concentrated under reduced pressure. The residue was purified with silica gel column chromatography (hexane/ethyl acetate=4:6) to give the title compound (7.74 g, yield 44%) as an oily matter.
