2-(2-Bromophenyl)acetaldehyde → 1-(2-Bromophenyl)butan-2-ol

Participants

Reaction Steps

To a solution of 2-(2-bromophenyl) acetaldehyde (15 g, 75.37 mmol) in THF (100 ml) was added propyl magnesium bromide (1.0 M in THF) (15.13 g, 113.6 mmol) at 0° C. then stirred at RT for 3 h. The reaction mixture was quenched with ammonium chloride then the title compound was purified by separation methods A, E and M. (Yield 7.0 g). The enantiomer showed up at tr=13.6 min with Chiralcel OJH (4.6×250 mm) 5μ, hexane:ethanol (98:02), 1 ml/min.
