A solution of N-{4-[4-(3-bromo-4-fluorophenyl)-5-oxo-4,5-dihydro-1,2,4-oxadiazol-3-yl]-1,2,5-oxadiazol-3-yl}-4-[(1,1-dioxidothiomorpholin-4-yl)methyl]-benzamide trifluoroacetate (20 mg, 28 μmol) in tetrahydrofuran (0.83 mL) was treated with 2.0 M of borane-dimethyl sulfide complex in toluene (42 μL, 85 μmol) was heated in the microwave at 130° C. for 5 min. The reaction mixture was treated with additional 2.0 M of borane-dimethyl sulfide complex in toluene (40 μL, 80 μmol) and heated in the microwave at 130° C. for 10 min. The reaction mixture was quenched with acetic acid, concentrated and purified by preparative LCMS to give the desired product (1 mg, 5%). LCMS for C21H23BrFN6O4S (M+H)+: m/z=553.0, 554.9.
