Participants

Reaction Steps

The dendrimer (DAB-Am-32; 185 mg; Mw: 3,514) dissolved in DMF (10 mL) then added PyBop (1.84 g; 2.1 eq; Mw: 520.4), followed by a solution of DBU (1 mL) and 3,6-disulfo-1-naphthoxyacetic acid (1.22 g; 2 eq; Mw: 362.3) in DMF (10 mL). The reaction mixture was left to stir overnight at R.T under N2. The solvent was removed under reduced pressure. Then purified through a sephadex (LH20) column followed by an Ion-exchange (IR120; Na+) and freeze-dried to yield SPL7320 as a white powder (402 mg, 48%).
