Procedure

To a solution of 4-(4-chloro-1-methyl-1H-pyrazol-5-yl)-N-((1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-{[2-(trifluoromethyl)phenyl]methyl}ethyl)-2-thiophenecarboxamide (150 mg, 0.262 mmol) in THF-MeOH (1:1, 2 mL) was added hydrazine (123 uL, 2.62 mmol). After 12 h, the solution was filtered and the filtrate was concentrated, dry loaded onto silica and purified via column chromatography (2% MeOH in DCM (1% NH4OH)) affording the free base of the title compound.
