Reaction Steps

To a solution of 5-fluoro-2-(1H-indazol-5-yloxy)-benzonitrile (44d) (0.200 g, 0.790 mmol) in DMF (6 mL) was added 2-chloro-N,N-dimethylacetamide (0.115 g, 0.948 mmol) and tetrabutyl ammonium iodide (0.088 g, 0.237 mmol), followed by K2CO3 (0.164 g, 1.19 mmol). The mixture was heated to 110° C. for 48 hours under N2 atmosphere. The reaction mixture was concentrated under reduced pressure and dissolved in dichloromethane. The solution was washed with 1N HCl, filtered, and chromatographed on Biotage eluting with 5% MeOH in dichloromethane to afford 0.032 g of the product (12% yield).
