Procedure

Crude (R)—N-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-((2,2-dimethyl-1,3-dioxolan-4-yl)methyl)cyclopropane-1-sulfonamide was dissolve in a mixture of THF (1 mL) and HCl (1.2N, 0.15 ml) and stirred overnight at room temperature. The solvents were removed under reduced pressure and the residue dissolved in ethyl acetate. The organic phase was washed with aqueous NaHCO3, dried (Na2SO4), and concentrated to afford (R)—N-(3,4-difluoro-2-(2-fluoro-4-iodophenylamino)-6-methoxyphenyl)-1-(2,3-dihydroxypropyl)cyclopropane-1-sulfonamide (1.4 mg, crude).
