실험 절차

1,1-Dimethylethyl 4-[2-[[(2,3-difluorophenyl)methyl]thio]-6-methoxypyrimidin-4-yl sulfamoyl]piperazine-1-carboxylate (the product of step i) (0.36 g) and trifluoroacetic acid (1 mL) in dichloromethane (4 mL) were stirred at room temperature for 30 min. The solvent was evaporated under reduced pressure and the residue was azeotroped with toluene (3×). The residual pale yellow solid was triturated with EtOAc, filtered and dried at 40° C. under high vacuum to give the title compound as a cream solid. Yield: 0.24 g.
