Chloromethyl Methyl Ether → HCID 59134395, compound

Participants

Reaction Steps

To a solution of 2-nitro-4-fluorophenol (1.6 g, 10.2 mmol) in tetrahydrofuran (32 mL), chloromethyl methyl ether (1.23 g, 15.3 mmol) and di-isopropyl ethyl amine (2.66 mL, 15.3 mmol) were added at room temperature, and the resulting mixture was stirred at room temperature for 1 hour. Upon the completion of the reaction, saturated ammonium chloride aqueous solution was added thereto, the resulting solution was extracted with ethyl acetate, washed with saturated sodium chloride solution, dried over magnesium sulfate, and concentrated. Sodium hydride (553 mg, 12.3 mmol) and 1-methyl-2-butyn-1-ol (1.23 mL, 12.7 mmol) were added to the solution of the resulting mixture in dimethylacetamide (17 mL) at 0° C., and the resulting mixture was stirred for 7 hours. Upon the completion of the reaction, saturated ammonium chloride aqueous solution was added thereto, the resulting solution was extracted with ethyl acetate, washed with saturated sodium chloride solution, dried over magnesium sulfate, and concentrated. The resulting mixture was purified by silica gel column (hexane/ethyl acetate=5/1) and the aimed product was obtained (yield: 94%).
