실험 절차

To a solution of 400 mg (1.52 mmol) of Z-N-Me-Val-OH, 300 mg (1.27 mmol) of Tyr(3-tBu)-NH2 and 230 mg (1.52 mmol) of HOBT in 7 ml of DMF, 0.24 ml (1.52 mmol) of DIC was added dropwise under cooling with ice and the mixture was stirred at room temperature for 15 hours and a half. The reaction mixture was diluted with ethyl acetate and washed with saturated brine. The organic layer was dried with anhydrous sodium sulfate and concentrated under reduced pressure; the resulting residue was subjected to silica gel column chromatography (eluting solvent consisting of methylene chloride, methanol and aqueous ammonia at a ratio of 100:3:1) to give 810 mg of Z-N-Me-Val-Tyr(3-tBu)-NH2.
