Reaction Steps
A solution (1 mol/L, 60 mL) of ethylmagnesium bromide in tetrahydrofuran was added to a solution (200 mL) of 2-bromobenzaldehyde (5.55 g, 3.0 mmol) in tetrahydrofuran under ice-cooling, followed by stirring for 1 hour while gradually heating the mixture to room temperature. Next, the reaction solution was poured into ice water, and this mixture was neutralized with hydrochloric acid (1 mol/L) and then extracted with ethyl acetate. After the extract was washed with a saturated brine and then dried over sodium sulfate, the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (developed with ethyl acetate/hexane=1/4) to give 1-(2-bromophenyl)-1-propanol (4.5 g, yield 70%).
