反応手順
To a stirred solution of 249.4 g (1 mole) of 4-(N-4-hydroxybutyl-N-butylamino)benzaldehyde in dichloromethane are added 153.1 g (1.5 moles) of acetic anhydride, 151.8 g (1.5 moles) of triethylamine, and 8.5 g (7 mole %) of 4-N,N-dimethylaminopyridine. The reaction mixture is stirred at room temperature for 16 hours. The product solution is washed with cold 2N HCl and then with filtered through cotton, and evaporated to dryness.
