실험 절차

(R)-3-(2,2-dimethyl-1,3-dioxolan-4-yl)prop-1-ene-2-sulfonyl chloride from STEP C was dissolved in pyridine (12 mL) and 5,6-difluoro-N1-(2-fluoro-4-iodophenyl)-3-methoxybenzene-1,2-diamine (2.56 g, 6.5 mmol) added. The solution was stirred at 100° C. for 2 hours and then partitioned with water and ethyl acetate. The organic layer was washed with brine, dried (MgSO4), concentrated under reduced pressure and purified by flash column chromatography on silica (30% ethyl acetate/hexanes eluant) to afford (R)—N-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-3-(2,2-dimethyl-1,3-dioxolan-4-yl)prop-1-ene-2-sulfonamide (651 mg, 17%).
