Reaction Steps

To a solution of 3-nitromethylheptanoic acid ethyl ester (10 g, 49.2 mmol) in methanol (100 mL) under argon was added Raney Ni (5 g). The mixture was stirred under 50 psi of hydrogen for 48 h, flushed with argon, filtered through a Celite pad, and concentrated under vacuum to afford 4-butylpyrrolidin-2-one as a colorless oil (6.3 g, 91%). MS(ES) m/e 142 [M+H]+.
