Chlorosuccinimide → 5-Bromo-2-(phenethyl)benzaldehyde

Participants

Reaction Steps

A mixture of 2-(N-(5-bromo-2-(phenethyl)benzyl)amino)-2-methylpropan-1-ol (9.13 g), N-chlorosuccinimide (3.38 g) and dichloromethane (50mi) was stirred for 4 hours. Alumina (10 g) was added and the mixture stirred for 6 days, filtered and the solvent evaporated. The residue was dissolved in dichloromethane (200 ml) and alumina (60 g) added in 6 portions over 8 hours. The mixture was filtered, the filtrate evaporated and the residue purified by MPLC eluting with dichloromethane/hexane (1: 1) to give 5-bromo-2-(phenethyl)benzaldehyde (3.54 g).
