Reaction Steps

A mixture of tert-butyl 2-(2-chlorooxazol-5-yl)-5-fluoro-1H-indole-1-carboxylate 50 (0.314 g, 0.934 mmol) and commercially available N-(3-aminophenyl)methanesulfonamide 6 (0.174 g, 0.934 mmol) in 2-propanol (20 mL) was heated to 80° C. for 18 h with stirring. Upon cooling, solvent was evaporated and silica column purified (Biotage) (Acetone/hexane as an eluent) to provide tert-butyl 5-fluoro-2-(2-((3-(methylsulfonamido)phenyl)amino)oxazol-5-yl)-1H-indole-1-carboxylate 52 (0.11 g, 25% yield) as solid. MS (ES) m/z 487 (M+H+).
