1-(2-nitro-6,7,8,9-tetrahydro-5H-benzo[7]annulen-7-yl)pyrrolidine → 7-(pyrrolidin-1-yl)-6,7,8,9-tetrahydro-5H-benzo[7]annulen-2-amine

Participants

Reaction Steps

A mixture of 1-(2-nitro-6,7,8,9-tetrahydro-5H-benzo[7]annulene-7-yl)pyrrolidine (2.0 g; 7.69 mmol) and 10% palladium on carbon (0.2 g, ˜50% water) in methanol (150 mL) was shaken under hydrogen (40 psi) for 1 h. After this time the reaction mixture was filtered through diatomaceous earth and the filtrate was concentrated under reduced pressure to afford 1-(2-amino-6,7,8,9-tetrahydro-5H-benzo[7]annulene-7-yl)pyrrolidine as an oil (quantitative yield); MS (m/e): 231 (M+H+).
