5-{4-[(E)-2-(1-Benzenesulfonylpyrrolidin-2-yl)-vinyl]-2-benzyloxyphenyl}-1,1-dioxo-1,2,5-thiadiazolidin-3-one → 5-{4-[2-(1-Benzenesulfonylpyrrolidin-2-yl)-ethyl]-2-hydroxyphenyl}-1,1-dioxo-1,2,5-thiadiazolidin-3-one

Participants

Reaction Steps

To a mixture of 5-{4-[(E)-2-(1-benzenesulfonylpyrrolidin-2-yl)-vinyl]-2-benzyloxyphenyl}-1,1-dioxo-1,2,5-thiadiazolidin-3-one (22 mg) in 4 mL ethanol/water (1:3) is added 5 mg of Degussa Pd/C and the resulting mixture is hydrogenated at 1 atm for 1 h. The catalyst is filtered through Celite and the solvent is removed under reduced pressure. The residue is purified by reverse phase Biotage using a gradient of 20-60% EtOH/water as eluent to furnish the title compound: LC retention time=1.10 min (Method A); (M−H)−=464.
