tert-butyl 5-nitro-2,3-dihydro-1H-isoindole-2-carboxylate → tert-butyl 5-amino-2,3-dihydro-1H-isoindole-2-carboxylate

Participants

Reaction Steps

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with tert-butyl 5-nitroisoindoline-2-carboxylate (650 mg, 2.5 mmol) and C2H5OH (50 mL). This solution was hydrogenated with Pd/C (160 mg) at room temperature for 15 h. It was then filtered and the filtrate was concentrated under reduced pressure to afford 231c as a yellow oil (585 mg, 99%), which was used in the next step without further purification. MS: [M+H]+ 179.
