Reaction Steps
To a solution of 2,6-diisopropylaniline (1.77 g, 10 mmol) in chloroform (30 ml) was added triethylamine (1.11 g, 11 mmole), then 4-bromobutyryl bromide (1.95 mg, 10.5 mmol) was slowly dropped thereinto with ice cooling and the mixture was made to react for 20 minutes. The reaction solution was diluted with water and extracted with chloroform. The organic layer was washed with 0.5N HCl, water, aqueous solution of sodium bicarbonate and 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 (120 g of silica gel; developing solvent, hexane:acetone=7:1→5:1) and the resulting crude crystals were recrystallized from hexane-acetone to provide 2.06 g (yield 63%) of 4-bromo-N-(2,6-diisopropylphenyl)butyramide as colorless needles.
