実験手順
WSC (4.2 g, 22 mmols) and HOBt (3.0 g, 22 mmols) were added to a DMF (40 ml) solution of the resulting carboxylic acid (5.2 g, 20 mmols) and 2,6-diisopropylaniline (5.3 g, 30 mmols), and stirred at room temperature for 12 hours. Water was added to the reaction mixture, and the precipitate formed was taken out through filtration, and extracted with chloroform. The organic layer was washed with 1 N HCl and saturated saline in that order, and dried with anhydrous sodium sulfate, and the solvent was evaporated. The residue was extracted with ether and filtered, and the filtrate was concentrated under reduced pressure. The residue was purified through silica gel column chromatography (developer: hexane/acetone=5/1) to obtain 1.9 g (yield: 23%) of N-(2,6-diisopropylphenyl)-15-hydroxypentadecanamide.
