실험 절차

In a round-bottomed flask, 374 mg of sodium hydride at 60% are introduced into 10 ml of tetrahydrofuran, 1g of (5-amino-2-fluorophenyl)methanol and 0.441 ml of methyl iodide. After stirring at ambient temperature for one hour, a solution of sodium chloride and diethyl ether are added. The organic phase is extracted and then washed with water until pH=7. It is then dried over magnesium sulphate, filtered, and concentrated under reduced pressure. 900 mg of 4-fluoro-3-(methoxymethyl)aniline are obtained in the form of a black oil, which is used as it is in the next stage.
