Versuchsvorschrift

Triethylamine (1.75 ml, 12.6 mmol) and triphenylmethyl chloride (3.50 g, 12.6 mmol) were added to a solution of 3-amino-2-azepanone (1.46 g, 11.4 mmol) in chloroform (44 ml) at room temperature and stirred overnight at room temperature. The reaction mixture was poured into water and then extracted with chloroform. The organic layer was washed with a saturated aqueous sodium chloride solution and then dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the resulting residue was purified by a silica gel column chromatography (eluent: chloroform/ethyl acetate) to obtain 3-(tritylamino)-2-azepanone (2.93 g, 69%).
