Reaction Steps

1.5 grams (3.77 mMoles) of Fmoc-citruline were dissolved in 3 mL of DMF in a round bottom flask to which was added 0.87 grams (4.5 mMoles) of EDC, 0.61 grams (4.5 mMoles) of HOBt. 6 mL of DCM were then added followed by the addition 0.88 grams (4.5 mMoles) of t-butyl-4-aminobenzoate and a catalytic amount of copper chloride. The reaction mixture was allowed to stir overnight The solvents were evaporated and the crude product purified over silica gel with 5 to 10% MeOH in DCM to give 2 grams of 4 in 92% yield. M+1=574
