Participants

Reaction Steps

To a solution of 3-[3-benzyloxy-4-(1,1,4-trioxo-1,2,5-thiadiazolidin-2-yl)-benzyl]-benzoic acid methyl ester (intermediate from Example LBY596) (0.3 g, 0.643 mmol) in THF is added a solution of LiOH (0.081 g, 1.929 mmol) in H2O. The reaction is stirred at ambient temperature overnight. The mixture is poured into 1 M HCl and extracted with EtOAc. The organic layer is dried over MgSO4, filtered and concentrated to afford a brown oil. The oil is place under high vacuum to afford solid 3-[3-benzyloxy-4-(1,1,4-trioxo-1,2,5-thiadiazolidin-2-yl)-benzyl]-benzoic acid: MS (M−H)−=451.2.
