反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 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). The solvents were removed under reduced pressure the residue dissolved in ethyl acetate The organic phase was washed with aqueous NaHCO3 dried (Na2SO4) concentrated
