Reaction Steps

210 mg (0.63 mMol) of 2 was treated with an HBr-ethyl acetate solution for 30 minutes. The solvent was evaporated and the resulting salt 3 was dried under high vacuum. The 0.63 mmol of 3 prepared above was reacted with 210 mg (0.69 mMol) of 4 in 10 mL of DMF in the presence of 133 mg (0.69 mMol) of EDC for 2 hours. The solvent was evaporated and the crude purified over silica. To give 160 mg of 5 (47.6% yield). M+1=518
