Reaction Steps
To a stirred solution of 0.40 g (1.3 mmols) of N-[2-(4-chlorophenyl)-1-(1,2,4-triazol-1-yl)-2-hexyl]formamide in 5 mL of methylene chloride under nitrogen was added 0.45 mL (3.26 mmols) of triethylamine. To this mixture was added a slurry of 0.439 g (1.63 mmols) of 3-ethyl-2-chlorobenzoxazolium tetrafluoroborate, which was weighed out under a nitrogen atmosphere, in 5 mL of methylene chloride. The reaction mixture was then allowed to stir at room temperature for 12 hours. The reaction mixture was poured into ice water and extracted with ethyl acetate. The combined organic layers were washed once with 10% hydrochloric acid, brine, and dried over magnesium sulfate. Removal of solvents gave a crude oil which was purified by column chromatography (Merck 60 silica gel, ethyl acetate/hexane) to give 0.20 g (52%) of a clear, colorless oil.
