1,4-Cyclohexadiene → 2-[4-(2-Methyl-oxazol-4-yl)-phenoxy]-ethylamine

참여 물질

반응 단계

A round-bottomed flask containing benzyl-{2-[4-(2-methyl-oxazol-4-yl)-phenoxy]-ethyl}-carbamate (788 mg, 2.07 mmol) was purged with nitrogen, and 10% Pd/C (200 mg, 20 wt %), ethyl acetate (15 ml), and methanol (5 ml) were added. 1,4-cyclohexadiene (0.90 ml, 9.60 mmol) was then added to the mixture, and the solution was allowed to stir at room temperature for about one hour. The reaction mixture was then filtered through a pad of diatomaceous earth and the filter cake was washed with methanol. The filtrate was concentrated in vacuo and the residue purified by column chromatography (silica gel; methylene chloride to 20% methanol/methylene chloride) to afford 456 mg (89% yield) of the desired product. LRMS ([M+H]+)=247.2.
