Versuchsvorschrift
10.9 g (50 mmol) of trimethyl-(2-nitrophenylethynyl)silane were dissolved in 200 ml of methanol, and 0.5 g of palladium-on-carbon (5%) were added. The mixture was then hydrogenated in an autoclave at 4 bar for 12 h. Removal of the solvent and column-chromatographic purification on silica gel 60 (mobile phase: methylene chloride) gave 4.1 g of 2-(2-trimethylsilylethyl)phenylamine [log P (pH 2.3)=2.58].
