Reaction Steps

The title compound was prepared in analogy to example 166, from (E)-5-(3-(4-bromophenyl)-3-(4-fluoro-2-methylphenyl)-1-(hydroxyimino)propyl)-1-methylpyridin-2(1H)-one (example 224) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzenesulfonamide (CAS RN 214360-51-7). The compound was purified by silica gel chromatography on a 20 g column using a MPLC system eluting with a gradient of dichloromethane:methanol (100:0 to 90:10). Light brown foam. MS (ESI+): m/z=520.2 ([M+H]+).
