Reaction Steps

In a microwave vial, 5-[3-{4-[(2-aminoethyl)amino]-1,2,5-oxadiazol-3-yl}-5-oxo-1,2,4-oxadiazol-4(5H)-yl]-2-fluorobenzonitrile hydroiodide (20.0 mg, 0.044 mmol) and sulfamide (25 mg, 0.26 mmol) were suspended in pyridine (0.5 mL). The reaction was heated to 120° C. for 10 minutes in a microwave reactor. The solvent was removed and the residue dissolved in methanol (0.17 mL). A solution of 2.0 N NaOH in water (0.22 mL, 0.44 mmol) was added in one portion. The reaction was stirred at room temperature overnight. After neutralization with acetic acid (50 μL), the product was purified using preparative LCMS to give the title compound (4.9 mg, 29%). LCMS for C12H14FN8O4S (M+H)+: m/z=385.0. 1H NMR (400 MHz, DMSO-d6): δ 11.65 (s, 1H), 9.08 (s, 1H), 7.34 (t, J=9.1 Hz, 1H), 7.22 (dd, J=5.4, 2.8 Hz, 1H), 7.13 (m, 1H), 6.70 (t, J=5.9 Hz, 1H), 6.59 (s, 2H), 6.20 (t, J=6.1 Hz, 1H), 3.34 (m, 2H), 3.09 (m, 2H).
