실험 절차

To a mixture of 20.0 g of 2-(3-hydroxypropyloxy)-5-trifluoromethylpyridine, 14.7 g of N-hydroxyphthalimide, 23.6 g of triphenylphosphine, and 200 ml of tetrahydrofuran was slowly added dropwise 20.0 g of diisopropyl azodicarboxylate with stirring under ice cooling in a stream of nitrogen gas. After stirring at room temperature for 24 hours, the reaction mixture was concentrated to give a residue. This residue was subjected to silica gel chromatography, which afforded 27.8 g (yield, 84%) of N-(3-(5-trifluoromethyl-2-pyridyloxy)propyloxy)phthalimide, m.p., 97.6° C.
