5-(1-((2-Chlorothiazol-5-yl)methyl)-5-methyl-1H-1,2,4-triazol-3-yl)-3-(4-(trifluoro methoxy)phenyl)-1,2,4-oxadiazole (45 mg, 0.1 mmol) was mixed with morpholine (87 mg, 1.0 mmol) in DMSO (0.5 mL). The mixture was heated to 140° C. overnight. The resulting crude product was purified by a silica gel column with (EtOAc/Hexane 50% to 100% EtOAc) to give 4-(5-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)-1H-1,2,4-triazol-1-yl)methyl)thiazol-2-yl)morpholine as a white solid (21 mg, 43%). MS (ES+) C20H18F3N7O3S requires: 493. found: 494[M+H]+; 1H NMR (600 MHz, CDCl3) δ 8.28 (d, J=8.8 Hz, 2H), 7.34 (d, J=8.4 Hz, 2H), 7.24 (s, 1H), 5.47 (s, 2H), 3.78 (t, J=4.9 Hz, 4H), 3.44 (t, J=4.9 Hz, 4H), 2.62 (s, 3H).
