Versuchsvorschrift

After dissolving 400 mg of 1-(tert-butoxycarbonyl)-4-(2-aminophenoxymethyl)piperidine in 10 ml of tetrahydrofuran, 124 mg of methyl isothiocyanate was added and the mixture was heated to reflux for 3.5 hours. The reaction solution was filtered with NH silica gel and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (solvent: n-hexane/ethyl acetate) to obtain the title compound (537 mg, 100% yield).
