Reaction Steps

The reaction mixture of 3-{[2-amino-5-({[bis(5-methoxy-5-oxopentyl)(oxido)-sulfanylidene]amino}carbonyl)pyridin-3-yl]ethynyl}benzoic acid (56 mg, 0.1 mmol, 1.0 equiv.), m-anisidine (13.4 μL, 0.12 mmol, 1.2 equiv.), DMAP (2.5 mg, 0.02 mmol, 0.2 equiv.) and EDC (29 mg, 0.15 mmol, 1.5 equiv.) in DCE (1 mL) in a sealed vial was stirred and heated at 60° C. for 3 hours. The resulting brown solution was diluted with EtOAc, washed with sat. aq. NaHCO3, aq. NH4Cl, and brine, and finally dried with anhydrous Na2SO4. The solution was decanted, concentrated, and the oily residue was subject to a gradient column chromatography (from EtOAc-Hex 1:4 to 6:1) to yield Dimethyl 5,5′-[N-({6-amino-5-[(3-{[(3-methoxyphenyl)amino]carbonyl}phenyl)ethynyl]pyridin-3-yl}carbonyl)sulfonimidoyl]dipentanoate
