Participants

Reaction Steps

To a solution of 3-{3-benzyloxy-4-[1,1,4-trioxo-5-(2-trimethylsilanylethyl)-1,2,5-thiadiazolidin-2-yl]-phenyl}-propionic acid (0.10 g, 0.2 mmol), EDCl (0.38 g, 0.20 mmol) and HOAt (0.027 g, 0.20 mmol) in DMF (1 mL) is added N-isopropyl-N-methylamine (0.15 g, 0.2 mmol). The mixture is stirred at RT for 18 h, then poured into water. The mixture is extracted into EtOAc and the organic phase washed with water (3×) and sat. NaCl (1×). The organic solution is dried over Na2SO4 and the solvent removed under reduced pressure to afford the title compound. This is used directly in the next step.
