Versuchsvorschrift

The title compound of Example 1, {2-[4-(4-Methyl-oxazol-2-yl)-phenoxy]-ethyl}-carbamic acid benzyl ester, (166 mg, 0.47 mmol) was dissolved in methanol (5 ml) and 10% Pd/C (50 mg) and 1,4-cyclohexadiene (192 mg, 2.4 mmol) were added to the resulting solution. The mixture was allowed to stir for about sixteen hours, and then it was filtered through diatomaceous earth, and the filter pad was washed with methanol. The filtrate was concentrated in vacuo to dryness, and the resulting material (92 mg, 90% yield), which was determined to be pure by 1H NMR, was used directly without further purification. LRMS ([M+H]+)=219.2.
