실험 절차

Dibenzylphosphoryl-L-alanyl-L-proline (1.4 g, 3.2 m mole), 1-hydroxybenzotriazol (476 mg, 3.5 m mole) and L-alanine benzylester p-toluene sulfonate (1.3 g, 3.5 m mole) were dissolved in DMF (5 ml), and WSC (0.64 ml) was added thereto while cooling to -15° C. The reaction was continued for 3 hours under cooling and then overnight at room temperature, and ethyl acetate (100 ml) was added thereto. The mixture was washed with 1N hydrochloric acid, 5% sodium bicarbonate and water in order, and dried with anhydrous sodium sulfate. The thus obtained solution was distilled under reduced pressure leaving an oily dibenzylphosphoryl-L-alanyl-L-prolyl-L-alanine benzylester material.
