実験手順

(S)-3-(2,2-dimethyl-1,3-dioxolan-4-yl)prop-1-ene-2-sulfonyl chloride (1 eq) is dissolved in pyridine and 5,6-difluoro-N1-(2-fluoro-4-iodophenyl)-3-methoxybenzene-1,2-diamine (1 eq) added. The solution is stirred at 100° C. for 2 hours and then partitioned with water and ethyl acetate. The organic layer is washed with brine, dried (MgSO4), concentrated under reduced pressure and purified by flash column chromatography on silica (30% ethyl acetate/hexanes eluant).
