Conditions

Temperature: 79 °C

Procedure

Pyrrolidine (1.81 mL, 21.8 mmol), was added to a suspension of ethyl 5-{[(1-methyl-1-phenylethyl)amino]carbonyl}-3-[(4-chloromethyl-benzoyl)amino]-1H-thieno[2,3-c]pyrazole-1-carboxylate (3.80 mg, 7.25 mmol) in 100 mL of dry ethanol. And the resulting mixture was stirred at 79° C. for 1 hour. Afterward the volatiles were removed by evaporation under reduced pressure and the residue was purified by chromatography over silica gel (eluant dichloromethane/methyl alcohol/aqueous ammonia 92:8:01) to give 1.2 g of the title compound.
