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

实验步骤: 6-Chloro-3-(2-ethoxy-3,4-dioxocyclobut-1-enylamino)-2-hydroxy-N-methoxy-N-methylbenzenesulfonamide (Intermediate A) (50 mg, 0.102 mmol) and 1,1,1,3,3,3-hexafluoroisopropylamine (34.0 mg, 0.203 mmol) were dissolved THF (1 ml). To the solution was added methanesulfonic acid (7 μl, 0.108 mmol) and the resultant mixture was heated at 50° C. overnight (˜18 hr). The solution was concentrated in vacuo and the residue was re-dissolved in DMSO (900 μl). The solution was transferred to a HPLC vial and purified using mass-directed prep system using 50-98% acetonitrile in water (0.1% TFA). The solvent was removed from the purified fraction in vacuo. The residue was re-dissolved in MeOH the solvent was removed in vacuo to afford the title compound as an orange solid; The solution was concentrated in vacuo the residue was re-dissolved in DMSO (900 μl) purified The solvent was removed from the purified fraction in vacuo The residue was re-dissolved in MeOH the solvent was removed in vacuo
