Reaction Steps

2.5 g (13 mmol) of 2-methyl-4-propionylbenzeneboronic acid are placed in 100 ml of dimethoxyethane in a round-bottomed flask, and 2.2 g (10 mmol) of 2-bromo-4-nitrotoluene and 13 ml of aqueous 2M potassium carbonate solution are added. The medium is degassed for 10 minutes with a flow of nitrogen, and 580 mg (0.5 mmol) of tetrakis(triphenylphosphine)palladium are then added. The medium is stirred for 14 hours at 90° C. and then worked up as usual. The residue is obtained after chromatography on a column of silica (eluent: 1 ethyl acetate/9 heptane) to give 2.3 g (81%) of the expected product in the form of a yellow oil.
