Reaction Steps

To a solution of 5-[4-(2-aminobenzyl)-2-benzyloxyphenyl]-1,1-dioxo-2-(2-trimethylsilanylethyl)-1,2,5-thiadiazolidin-3-one (Example 4, Step A) (250 mg, 0.478 mmol) in pyridine (1.5 mL) is added acetylchloride (41 mg, 0.525 mmol). The mixture is stirred at ambient temperature for 30 min., then diluted with EtOAc and washed with 0.5N HCl, saturated NaHCO3 and brine. It is then dried over Na2SO4/MgSO4, filtered and concentrated to afford N-(2-{3-benzyloxy-4-[1,1,4-trioxo-5-(2-trimethylsilanylethyl)-1,2,5-thiadiazolidin-2-yl]-benzyl}-phenyl)-acetamide as a gum: MS (M+H)+=566.1.
