Benzene → 2-Bromobiphenyl

Participants

Reaction Steps

A solution of 8.8 mL of isoamylnitrite in 120 mL of benzene at 45° C. was treated dropwise over 30 minutes with a solution of 7.5 g of 2-bromoaniline in 30 mL of benzene. After the addition was complete, the mixture was heated at reflux for 90 minutes then cooled and concentrated under vacuum. The product was purified by preparative high presssure liquid chromatography on silica, eluting with hexanes. 1H NMR (200 MHz,CDCl3): 7.23 (m,2H), 7.35 (m,1H), 7.44 (s,5H), 7.70 (d,8 Hz,1H).
