実験手順
WSC (1.05 g 5.5 mmols) and HOBt (743 mg, 5.5 mmols) were added to a DMF (15 ml) solution of 2,6-diisopropylaniline (886 mg, 5 mmols) and 8-bromooctanoic acid (1.67 g, 7.5 mmols), and stirred at room temperature for 12 hours. The reaction mixture was extracted with ether. The organic layer was washed with water, 1 N HCl, an aqueous saturated solution of sodium hydrogencarbonate and saturated saline in that order, and dried with anhydrous magnesium sulfate, and the solvent was evaporated. Then, the residue was purified through silica gel column chromatography (developer:hexane/acetone=5/1), and the resulting crystals were recrystallized from other-hexane to obtain 720 mg (yield: 38%) of 8-bromo-N-(2,6-diisopropylphenyl) octanamide as colorless needle-like crystals.
