실험 절차

A mixture of 5-chloro-N-((1-(4-iodophenyl)-1H-imidazol-4-yl)methyl)thiophene-2-carboxamide 1-6 (70 mg, 0.16 mmol), N-ethylpiperazine-2,3-dione (45 mg, 0.32 mmol), N,N′-dimethylethylenediamine (0.020 mL, 0.19 mmol) and K2CO3 (65 mg, 0.47 mmol) in DMSO (1 mL) and dioxane (1 mL) was degassed with Ar before being charged with CuI (20 mg, 0.10 mmol). The mixture in a sealed tube was heated at 110° C. overnight. The mixture was then purified by HPLC to give the titled compound (10 mg). MS 458.1 and 460.1 (M+H, Cl pattern).
