Potassium Carbonate → tert-Butyl 1-(1-(3-fluorobenzyl)-1H-imidazol-2-yl)-2-(7-methyl-2-((2-(trimethylsilyl)ethoxy)methyl)-2H-indazol-5-yl)ethylcarbamate

Participants

Reaction Steps

A mixture of tert-Butyl-1-(1H-imidazol-2-yl)-2-(7-methyl-2-[{2-[trimethylsilyl]ethoxy}methyl]-2H-indazol-5-yl)ethylcarbamate (20 mg, 0.042 mmol), 3-fluoro benzyl bromide (5.5 μL, 0.045 mmol, 1.1 equiv), and potassium carbonate (11.7 mg, 0.09 mmol) in dimethylformamide (0.6 mL) was stirred at room temperature for 16 h. The solvents were removed in vacuo and the residue purified by column chromatography to afford 15.2 mg (63%). Mass spec.: 580.04 (MH)+.
