Sodium hydride (0.013 g, 0.53 mmol) was added portionwise to a stirred solution of 5-(2-methoxypyridin-4-yl)-N,4-dimethyl-4H-1,2,4-triazol-3-amine (0.086 g; 0.39 mmol) in DMF (10 ml) at 0° C. The mixture was stirred for 30 minutes before [5-(3-cyanophenyl)-1,2,4-oxadiazol-3-yl]methyl methanesulfonate (0.1 g; 0.36 mmol) in DMF (1 ml) was added dropwise. The mixture was stirred at r.t. for 3 h before quenching with water (30 ml). The resulting mixture was extracted with EA (3×40 ml). The organics were combined, dried (Na2SO4) and evaporated to give a crude material, which was purified by prep. HPLC to give the title compound (0.061 g; 42.3%). 1H NMR: 8.49 (s, 1H), 8.33 (dd, 1H), 8.28 (d, 1H), 7.86 (dd, 1H), 7.67 (t, 1H), 7.24 (d, 1H), 7.02 (s, 1H), 4.60 (s, 2H), 3.97 (s, 3H), 3.70 (s, 3H), 3.08 (s, 3H).
