Reaction Steps

tert-Butyl-1-(1H-imidazol-2-yl)-2-(7-methyl-2-[{2-[trimethylsilyl]ethoxy}methyl]-2H-indazol-5-yl)ethylcarbamate (25 mg, 0.53 mmol), (2-bromoethyl)benzene (7.5 μL, 0.056 mmol, 1.05 equiv), and potassium carbonate (14.7 mg, 0.106 mmol) were combined in dimethylformamide (1.0 mL). After stirring at room temperature for 16 h, the solvents were removed and the residue purified by column chromatography to afford 9.0 mg (29%). Mass spec.: 576.5 (MH)+.
