Komponenten

Versuchsvorschrift

Triethylamine (111 mg, 1.1 mmol) was added to a solution of 2,4,6-triisopropylaniline (219 mg, 1.0 mmol) in chloroform (3 ml), then bromoacetyl bromide (222 mg, 1.1 mmol) was gradually dropped thereinto with ice-cooling and the mixture was stirred for 1 hour. The reaction mixture was concentrated and the residue was extracted with ethyl acetate. The organic layer was washed with diluted hydrochloric acid, an aqueous solution of sodium bicarbonate and a saturated sodium chloride solution successively and dried over magnesium sulfate and the solvent was evaporated therefrom. The residue was purified by a silica gel column chromatography (15 g of silica gel; developing solvent, hexane:acetone=5:1) followed by recrystallizing from hexane-ether to provide 275 mg (yield 81%) of 2-Bromo-N-(2,4,6-triisopropylphenyl)acetamide as colorless needles.
