To a solution of Boc-ΔTyr(Cl2Bzl)-OH (307 mg, 0.7 mmol), glycinamide hydrochloride (77.4 mg, 0.7 mmol) and Et3N (0.1 mL, 0.7 mmol) in DMF (7 mL) is added EDC·HCl (148 mg. 0.77 mmol) and HOBt (129 mg, 0.84 mmol) at -10°C. The reaction mixture is stirred for 2 h at 0°C. and overnight at room temperature. After the solution is evaporated, the residual is dissolved in EtOAc. The solution is washed with 4% NaHCO3, 10% citric acid and water. The solution is dried and evaporated. The purification is carried out by silica gel column chromatography to give Boc-ΔTyr(Cl2Bzl)-Gly-NH2 (317 mg, 85% yield).
