Procedure

To a solution of 3-{3′-[5-(tert-butoxycarbonylamino-imino-methyl)-2-methylsulfanyl-thiophene-3-sulfonyl]-6-methyl-biphenyl-2-ylmethoxy}-propionic acid ethyl ester (7.0 mg, 11 μmol) in THF (0.5 mL) and MeOH (0.25 mL) was added a solution of lithium hydroxide monohydrate (0.56 mg, 13 μmol) in H2O (50 mL). The mixture was microwaved at 80° C. for 150 seconds, acidified with 0.25 N HCl to ˜pH 3, extracted with EtOAc/DCM (1:1, 3×). The extracts were combined, washed with H2O, dried over Na2SO4, concentrated, and flash chromatographed on silica gel column, eluting with MeOH/DCM (2 to 4%) to give the title compound (5.1 mg, 76% yield) as a white solid.
