A 4 mL vial was charged with 4-acetyl-N-(4-chloro-2-[1,2,3]triazolo[4,5-b]pyridin-1-yl-phenyl)benzenesulfonamide (synthesized according to general procedures F and G, 100 mg, 0.23 mmol) and 1.5 mL THF. The resultant slurry was cooled to −78° C. in a dry ice-acetone bath, 2.0 M methylmagnesium bromide in Et2O (350 μL, 0.70 mmol) was added dropwise, and the mixture was stirred for five hours. The reaction mixture was subsequently diluted with ˜2 mL of acetonitrile/H2O and purified by reversed phase HPLC to afford N-(4-chloro-2-[1,2,3]triazolo[4,5-b]pyridin-1-yl-phenyl)-4-(1-hydroxy-1-methyl-ethyl)-benzene-sulfonamide: MS (ES) M+Na expected 466.0, found 466.0.
