実験手順

Add lithium carbonate (49 mg, 0.66 mmol) and 5-chloromethyl-3-(3-iodo-benzyl)-[1,2,4]oxadiazole (200 mg, 0.60 mmol) to a solution of 1-(2,4-dihydroxy-3-methyl-phenyl)-ethanone (110 mg, 0.66 mmol) in anhydrous dimethylformamide (20 mL) 4]oxadiazole (200 mg, 0.60 mmol). Heat the reaction mixture at 60° C. overnight. Cool the reaction mixture to RT, pour into H2O, and extract with diethyl ether (3×). Combine the organic layers, wash with brine, dry over sodium sulfate, and concentrate to provide the title compound (150 mg). LC-MS (m/e): 463 (M−1).
