Reaction Steps

To a solution of methanesulfonic acid 2-[3-benzyloxy-4-(5-benzyloxymethyl-1,1,4-trioxo-1,2,5-thiadiazolidin-2-yl)-5-fluorobenzyl]-4-methylphenyl ester (85 mg) in EtOH (3 mL) and EtOAc (6 mL) is added 5% Pd/C (75 mg) and the mixture is hydrogenated at 1 atm for 18 h. The catalyst is filtered and washed with EtOH (3×). Solvent is evaporated to near dryness before water and acetonitile is added to form a solution. It is then lyophilized to give the title compound: MS (M−H)−=443.
