Reaction Steps

5-(1-((2-Chloropyridin-4-yl)methyl)-5-methyl-1H-1,2,4-triazol-3-yl)-3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazole (50 mg, 0.115 mmol) and morpholine (100 mg, 1.15 mmol) were dissolved in DMSO (0.5 mL) in a sealed tube reaction vessel. The reaction was heated at 130° C. overnight and then cooled to RT. The reaction was then filtered and purified by prep-HPLC (MeCN/H2O 30%—MeCN 70% containing 0.1% TFA). The product was taken up in EtOAc (10 mL), washed with sat. NaHCO3 (10 mL), dried over Na2SO4, filtered, and concentrated to afford 4-(4-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)-1H-1,2,4-triazol-1-yl)methyl)pyridin-2-yl)morpholine as a yellow solid (35 mg, 63%).
