A solution of lithium aluminum hydride (a 1.0M solution in THF; 4.22 ml, 4.22 mmol) was added slowly to a solution of 4-(1-azidotridecyl)-2-triethylsilylfuran (1.55 g, 3.84 mmol) at 0 degrees C. under argon. After stirring at room temperature for 2 hours, the mixture was cooled to 0 degrees C. and quenched with 2M sodium hydroxide. Anhydrous sodium sulfate was added to coagulate the aluminum salt and the mixture was extracted thoroughly with ethyl acetate. Evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by flash chromatography on silica using 5% methanol/dichloromethane to give the titled amine.
