実験手順
To a suspension of 4-nitrobenzylamine hydrochloride (10.0 g) and triethylamine (22.2 ml) in acetonitrile (100 ml) was added trifluoroethyl acetate (12.6 ml) at room temperature and the mixture was stirred for 24 hours. The solvent was removed under reduced pressure, water was added to the mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure. The precipitated crystals were collected by filtration. The crystals were washed with hexane, to give N-(4-nitrobenzyl)trifluoroacetoamide (12.79 g) as colorless crystals.
