(4-formyl-2-methylphenyl)boronic acid

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: In a manner similar to that of Example 1(e), by reacting 6.1 g (20.3 mmol) of tert-butyl (3-bromo benzyl)-N-methylcarbamate with 4.3 g (26.2 mmol) of 2-methyl-4-formylbenzene boronic acid, and after purification by chromatography on a column of silica eluted with a heptane/ethyl acetate mixture (8/2), 4 g (58%) of the expected product are obtained in the form of an orange oil. after purification by chromatography on a column of silica eluted with a heptane/ethyl acetate mixture (8/2), 4 g (58%) of the expected product are obtained in the form of an orange oil
