실험 절차

A solution of 5-chloro-N-[4-(methyloxy)-1H-indazol-3-yl]-N-({[2-(trimethylsilyl)ethyl]oxy}methyl)-2-thiophenesulfonamide (for a preparation see Intermediate 8) (1 g, 2.11 mmol) in DMF (10 mL) was treated at ambient temperature with potassium carbonate (0.583 g, 4.22 mmol) and methyl 3-(bromomethyl)benzoate (Alfa Aesar) (0.580 g, 2.53 mmol). The resulting mixture was stirred at 50° C. for 2 h and the LCMS then showed product as the major peak. The mixture was diluted with DCM (20 mL) and of water (20 mL). The organic phase was separated and the aqueous layer was further extracted with DCM (20 mL). The combined organic solutions were washed with brine (30 mL), dried over an hydrophobic frit, and concentrated under reduced pressure.
