Chloromethyl Methyl Ether → HCID 22344490, Verbindung

A solution of 5-hydroxyquinoline (10.3 g) in dimethylformamide (140 ml) was ice-cooled. To the solution was added sodium hydride (3.0 g, 62.6% in oil) and the mixture was stirred at 0° C. for 15 minutes. To the reaction mixture was added methoxymethyl chloride (6.5 ml) and then the mixture was stirred at 0° C. for 2 hours. To the reaction mixture was added ice. The reaction mixture was stirred and then diluted with water. The aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with 1N aqueous solution of sodium hydroxide, water and a saturated aqueous solution of sodium chloride subsequently, dried over anhydrous magnesium sulfate, and then concentrated to give the title compound (10.4 g) having the following physical data. The obtained compound was used without purification in the subsequent reaction.
