실험 절차

To 5 ml of chloroform dissolving 50 mg (0.19 mmol) of dinitrophenylaminobutyric acid (mfd. by Sigma Chemical Co.), 40.8 μl (0.38 mmol) of N-methylmorpholine (mfd. by Wako Pure Chemical Industries, Ltd.) and 36.1 μl (0.29 mmol) of isobutyl chloroformate (mfd. by Wako Pure chemical Industries, Ltd.) were added and reacted at 0° C. for 30 minutes with stirring. To this, 120 mg (0.13 mmol) of the Nα --BOC--L-lysine.DPPE condensate obtained in above i) was was added and reacted at room temperature overnight with stirring. After the reaction, the solvent was removed by distillation, followed by purification using a silica gel column (eluent: a mixed solvent of chloroform and methanol) to give 82 mg of Nα --BOC--Nε -dinitrophenyl-L-lysine.DPPE condensate (yield 54%).
