実験手順

To a 250 mL round-bottomed flask was added 5-chloro-N-{(1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-[(3-fluorophenyl)methyl]ethyl}-4-(1-methyl-1H-pyrazol-5-yl)-2-thiophenecarboxamide (7.8 g, 14.91 mmol) and hydrazine (14.50 ml, 298 mmol) in tetrahydrofuran (THF) (75 ml) and methanol (75 mL). After 24 h at RT, the precipitate was filtered, the filtrate was concentrated. The crude product was purified on a silica gel column [CHCl3/MeOH/NH4OH, 90:9:1] to give the title compound as a white solid.
