실험 절차

A solution of 4-(3-bromo-4-fluorophenyl)-3-[4-({4-[(1,1-dioxidothiomorpholin-4-yl)methyl]benzyl}amino)-1,2,5-oxadiazol-3-yl]-1,2,4-oxadiazol-5(4H)-one trifluoroacetate (10 mg, 14 μmol), zinc cyanide (5 mg, 43 μmol), and tetrakis(triphenylphosphine)palladium(0) (8 mg, 7 μmol) in N,N-dimethylformamide (0.25 mL) was heated in the microwave at 150° C. for 5 min. The reaction mixture was diluted with 3:1 acetonitrile/water (2 mL), filtered, and purified by preparative LCMS to give the intermediate 5-[3-[4-({4-[(1,1-dioxidothiomorpholin-4-yl)methyl]benzyl}amino)-1,2,5-oxadiazol-3-yl]-5-oxo-1,2,4-oxadiazol-4(5H)-yl]-2-fluorobenzonitrile trifluoroacetate. This material was diluted with ethanol (1 mL), treated with 2.0 M sodium hydroxide in water (0.1 mL), and stirred for 45 min. The reaction mixture was quenched with acetic acid (50 μL, 0.9 mmol), filtered, and purified by preparative LCMS to give the desired product (1 mg, 11%). LCMS for C22H23FN7O4S (M+H)+: m/z=500.0.
