실험 절차

To a stirred, ice-water chilled suspension of potassium hydride (0.680 gm; 5.95 mmol) in 15.0 ml of tetrahydrofuran is added a mixture of 1-aminoadamantane-3-ol (1.00 g; 5.95 mmol) and 15.0 ml of tetrahydrofuran dropwise over 30 minutes. The resulting mixture is then stirred for an addition 30 minutes and iodomethane (0.370 ml; 5.95 mmol) is then added dropwise over one minute. The resulting opaque white reaction is then stirred at room temperature for 18 hours. The mixture is then diluted with 50 ml of methylene chloride and filtered to remove the inorganic impurities. The filtrate is then concentrated and purified on silica gel employing a SIMS/Biotage apparatus and 19% methanol and 1% ammonium hydroxide in methylene chloride as eluent to yield 3-methoxy-1-adamantylamine as an opaque oil.
