A mixture of methyl 3-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)-1H-1,2,4-triazol-1-yl)methyl)benzoate (46 mg, 0.1 mmol) and 3-methoxylpropylamine (27 mg, 0.3 mmol) was treated with 1,2,4-triazole (7 mg, 0.1 mmol) and DBU (15 mg, 0.1 mmol), and heated to 70° C. overnight. The crude product was purified by a silica gel column with EtOAc to give N-(3-methoxylpropyl)-3-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)-1H-1,2,4-triazol-1-yl)methyl)benzamide as a white solid (45 mg, 87%).
