Procedure
A solution 5-[1-(4-Chloro-2-trifluoromethyl-benzyl)-1H-indazol-5-ylmethylene]-2-[1,4]diazepan-1-yl-thiazol-4-one (0.016 g, 0.03 mmol) in acetonitrile (1.5 mL) was treated with potassium carbonate (0.022 g, 0.15 mmol) and 1-bromo-2-fluoro-ethane (0.04 g, 0.3 mmol). Reaction mixture was stirred at 70° C. for 18 hours and the solvent evaporated in vacuo. The residue was partitioned between dichloromethane and water. The dichloromethane layer was washed with brine, dried over Na2SO4, filtered, and the solvent evaporated in vacuo to yield a crude solid. The crude solid was purified via flash chromatography (5% methanol in dichloromethane) to yield the title compound (17 mg, 100%).
