Reaction Steps
To a dry DMF solution of 2,6-diisopropyl-4-bromophenylacetaldehyde (7.3 g, 25.8 mmol) at 0° C. was added 2,6-ditert-butyl-4-methylphenol (0.056 g, 0.26 mmol), followed by NBS (4.59 g, 25.8 mmol). After stirring for few minutes, benzenesulfonic acid (8.16 g, 51.6 mmol) was added. The resulting mixture was stirred at 35° C. for 12 h under nitrogen. After regular work up, the crude product was purified by column chromatography to afford 2-(2,6-diisopropyl-4-bromophenyl)propionaldehyde (5.4 g).
