Procedure
A solution of 4-[2-tert-butyl-5-(4-chloro-benzyl)-2H-pyrazol-3-ylamino]-N-thiazol-2-yl-benzenesulfonamide (20 mg, 0.04 mmol, 1.0 equiv) was heated in 1.0 mL of formic acid at 95° C. After 16 h, the reaction mixture was concentrated in vacuo. The residue was purified via automated flash chromatography (4 g SiO2, gradient from chloroform to 12% methanol in chloroform) to afford the product as an off-white solid (7 mg, 40%).
