30 mg of 3-(2-Amino-benzoylamino)-thieno[2,3-c]pyrazole-1,5-dicarboxylic acid 5-tert-butyl ester 1-ethyl ester (0.058 mmol) were treated with a 10% solution of TEA and methanol (8 mL) at room temperature for 3 hours. The solvent was removed under vacuum and the residue was purified by flash chromatography (eluant dichloromethane/methanol 99/1) yielding 19 mg (91%) of the title compound.
