実験手順

3-chloro-5-[(5-chloro-1H-1,2,3-benzotriazol-4-yl)oxy]benzonitrile (100 mg, 0.328 mmol), cesium carbonate (107 mg, 0.328 mmol) and 2-(chloromethyl)-5-phenyl-1,3,4-oxadiazole (64 mg, 0.328 mmol) were combined and suspended in DMF (2 mL). After 16 hours at room temperature, the reaction mixture was quenched with saturated aqueous ammonium chloride (1 mL) and extracted with EtOAc (2×25 mL). The combined organic fractions were evaporated under reduced pressure, and the resulting residue was purified by reverse phase chromatography eluting with 30-95% MeCN/H2O+0.1% TFA. The product fractions were concentrated to yield the title compound. 1H NMR (DMSO-d6) δ 8.01 (d, J=8.9 Hz, 1H), 7.96 (d, J=8.3 Hz, 2H), 7.88 (d, J=8.9 Hz, 1H), 7.83 (m, 1H), 7.61 (m, 5H), 6.54 (s, 2H). HRMS (M+1)=463.0465.
