To a stirred solution of Z-Arg.HCl (5.17 g, 15 mmoles) in dimethylacetamide (25 mL) at 25° C. was added a solution of HCl.Pro-Asp(OBzl)-Pro-Phe-NH2 and N-methylmorpholine (1.65 mL, 15 mmoles) in dimethylacetamide (25 mL). To the resulting solution, diethyl cyanophosphonate (2.45 g, 15 mmoles) and N-methylmorpholine (1.65 mL, 15 mmoles) were added and the mixture stirred for 4 hours. The reaction was quenched by the addition of 10% aqueous acetic acid (10 mL) and the solvents were removed on a rotary evaporator under reduced pressure. The resulting solid was triturated with 10% potassium carbonate and then with water and filtered.
