Procedure

In 30 ml of tetrahydrofuran was suspended 75 mg (2 mmol) of lithium aluminum hydride. While this suspension was held under ice-cooling, 1.03 g (1.7 mmol) of 2,3-dioleyloxypropyl azide was added dropwise and the mixture was stirred for 30 minutes. Then, the mixture was further stirred at ambient temperature for 2 hours. At completion of the reaction, the reaction mixture was poured in ice-water and extracted with ether and the extract was washed with water, dried, and concentrated. The residue was subjected to column chromatography (silica gel/methylene chloride-methanol) to provide 0.98 g (98%) of the title compound as colorless oil.
